The best weapon in the “Jackass’” arsenal isn’t the taser, the beehive or the booby-trapped latrine. It’s the explosion of relief when a prank ends, often in humiliation, always with hoots and claps. The first film, 2002’s “Jackass: The Movie” was slow to discover that carnage without camaraderie is painful; several injuries limped off-screen in horrified silence. Laughter heals, except for the brain hemorrhage that Johnny Knoxville suffered in 2022’s “Jackass Forever” when, dissatisfied by the clobbering he took from a bull, requested a second ramming that knocked him out cold.

Hence “Jackass: Best and Last,” the goon squad’s alleged final film, is underwhelmingly tame. Shot quickly by stalwart director Jeff Tremaine this spring, half of it is a clip reel of past hits, like the time fan favorite Steve-O slingshotted into the sky in a port-a-potty. The rest is scraps of hastily assembled chaos, the most elaborate of which is a puppet show in which veterans Ehren McGhehey, Dave England and Jason “Wee Man” Acuña dangle helplessly from strings, trying to recite cue cards while being pummeled by tropical fruit. “A pineapple!” Wee Man moans.

I’m no sadist. They’ve suffered plenty for our amusement. Still, it’s a shame that for the first time in two and a half decades of cringe comedy, the guffaws feel forced.

Acknowledging the Jackasses’ age, if not maturity, are a couple skits about prostate and rectal checkups. (The gnarliest involves clear pants, colonoscopy prep liquid and a game of Twister.) Modern technology enters the arena with a nimble-fingered robot. If the team had invested any actual energy into brainstorming this entry, they’d have played paintball with a sniper drone. At least for the sake of torch-passing, someone should have thought of something for the newish members introduced in “Jackass Forever” to do besides stand around and applaud.

These fresher faces — Jasper Dolphin, Rachel Wolfson, Zach Holmes — prove brave and resilient when allowed to participate. Only one of them, Sean “Poopies” McInerney, a surf bro so gullible that I’m not sure he’s capable of informed legal consent, fits into “Best and Last” like a well-worn punching bag. (When Poopies yelps that “my mind is getting to me” while wearing a shock collar around a sensitive area, people snort because, as sweet as he seems, the only thing rattling inside his cranium is a moth.) Early on, Poopies gets swollen lip injections that, someone claims, will last the whole movie. You expect his trophy wife pout to be a running sight gag. But his disfigurement never even gets another closeup.

“Jackass” started with a bang. In January of 1998, Knoxville, then a 26-year-old aspiring actor, strapped on a cheap bulletproof vest padded with a stack of “Hustler” magazines and fired a gun point-blank into his chest. His dumb derring-do went viral on VHS tapes, earning him an MTV show and five feature films. Watching that Rosetta Stone-cold stupid footage here, you’re struck not only by his audacity, but by the scene’s excruciating comic pacing. As there’s only one bullet in the pistol, empty chambers click multiple times before the bullet finally fires. Logically, you know Knoxville will live long enough for his hair to turn fright-wig white. Yet the lizard brain making you gawk is shrieking.

Do not attempt any of the stunts you’re about to see, the prefatory caution blares. Absolutely. The thing is, no one else could. “Best and Last’s” flashbacks are a walloping reminder that Knoxville is inimitable: a telegenic and extroverted entertainer with a charisma he wields like a skunk aims its stink. Upset him at your own risk. Like Buster Keaton before him, Knoxville has an uncanny awareness of how his death-defying escapades appear on camera. Even in that near-suicidal early segment, note how Knoxville stays on his feet, enduring agony with a magician’s “Ta-da!” He might have given himself a bruise the size of a baseball but he’s focused on the audience’s delight.

Over the years, the visuals dramatically improve, from snuff film aesthetics to confidently silly splendor. “Jackass Number Two,” released in 2006, expended major energy on a musical homage to Old Hollywood that nodded to Keaton and bathing beauty Esther Williams who, in MGM’s “Million Dollar Mermaid,” plunged 50 feet into a pool and broke her neck. By 2010’s “Jackass 3D,” which riffed on classic cartoons with Knoxville strapping himself onto an Acme-style red rocket, one could admit they went to see a Jackass movie for the cinematography with even more sincerity than if Knoxville claimed he bought “Hustler” for its life-saving properties.

The new movie doesn’t have any artistic ambition. The charitable excuse for its reliance on old material is that the gang wanted one more film that summed up their entire legacy — from the impact of seeing them age to the opportunity to include departed colleagues Ryan Dunn, who died in 2011, and Bam Margera, fired in 2020. The other explanation is it’s a cash grab made for pennies. Still, Steve-O strives for memorable moments, gathering the gang in a generic office building corridor to watch him take off his pants and pop out a ping-pong ball. There’s a lot of nudity but the setting feels half-assed.

“Best and Last’s” intro splat-tacular, typically a highlight of each film, hinges on the posse standing still on a moving floor. But the monochrome staging — white walls, white ground — looks almost like CGI, the antithesis of their appeal, and it takes us a minute to understand what’s actually going on. Worst, it lacks both suspense and surprise, that no-they-aren’t–oh-god-they-are drama that once elevated the franchise to the peak of pure cinema.

There is — and I mean this — existentialism in witnessing a person embrace shame and terror. Actors have won Oscars without achieving the transcendence of, say, misery glutton McGhehey in “Jackass Forever,” bound to a chair and coated in salmon and honey, realizing that his friends have released a bear into the room. Meryl Streep could never do that (and wouldn’t have to). McGhehey’s sole path to stardom is that he did.

Not everything in a “Jackass” movie needs to be that sublime. One of my few genuine howls in “Best and Last” came in a three-second rehash of someone stepping on a rake; another was the percussion Chris Pontius makes with his swinging nethers before attempting a naked Fosbury flop. There’s a great accidental gag in a cut bit from the original MTV pilot when a deputy pulls up to arrest Knoxville and forgets to put her car in park. Yet the snippet I keep thinking about is a throwaway beat in a new skit when McGhehey willingly gets into the wrong chair again and, once freed, attacks Knoxville who coolly knees him in the nuts. Everyone chuckles.

Once, in anthropology class, my professor lectured on an insular island tribe that cackled whenever someone got hurt. Schadenfreude was the community’s way to vent tension. I thought of that village throughout “Best and Last,” especially during Knoxville’s nonchalant disarmament of his pal. Team Jackass has stayed united even while at each other’s throats. In bad times, they’ve borne each other’s struggles with sobriety and mental health. In good, they’ve seen the inequality of success that’s left Knoxville in a better financial position to retire than the rest.

While “Best and Last” is a whiff, I can forgive this band of bozos’ urge to make it. No one seems happy to still be zapping themselves with electrodes. They just want to rally together for the final time to choke out one last laugh.

When David Jacks published a biography of Peter Asher in 2022, the veteran record producer and manager expressed surprise that anyone would have deemed his life worthy of the treatment. Four years later, he’s no less baffled to have become the subject of a new documentary, “Peter Asher: Everywhere Man,” directed by the filmmakers Dan Geller and Dayna Goldfine.

“It just seemed to me,” he says, “that I wouldn’t be that fascinating.”

The movie, in theaters now, argues otherwise: A child actor alongside his two younger sisters, the bespectacled Asher became an unlikely pop star during the British invasion as half of the duo Peter & Gordon, whose debut single, “A World Without Love” — written by Paul McCartney — hit No. 1 on Billboard’s Hot 100 in 1964. (McCartney offered the song to Asher while the Beatle was dating Asher’s sister Jane.) In 1968, the Beatles made Asher head of A&R at Apple Records, where he signed James Taylor; the two soon moved to Los Angeles and turned Taylor into music’s biggest heartthrob folkie.

Asher went on to shepherd Linda Ronstadt to stardom and to produce records by Diana Ross, Cher, Bonnie Raitt, Randy Newman, Neil Diamond and 10,000 Maniacs, among many others. And at 82 he’s still at it: Last year he produced Barbra Streisand’s latest duets album — they’re due to start work on a new Streisand solo LP, he says — and he’ll perform a show of his own July 19 at the Grammy Museum. Asher, who broke his leg in a recent fall, spoke about it all the other morning at his home in Malibu, where he walked into the kitchen using a cane before sitting down at a table set with pastries and several of the day’s newspapers.

What unites the jobs of musician, producer, executive, manager? What’s the through line?
Love of music and admiration for the people who do it. They’re very different jobs, and I came at them from very different perspectives. Record production was something I set out to do once I understood what a record producer did. Hire musicians much better than yourself and tell them what to do? That’s a cool job — how do I get in on that racket? Whereas I never had any ambitions to be a manager. It’s just that when James and I decided to go out on our own and try to put a career together, we didn’t know who we trusted to do it, so I kind of went, I’ll do it.

What’d you discover about the job of management?
The ingredients are common sense, not being a crook and having a great client.

Which is the hardest of those three?
The last one. I got to induct the first managers inducted into the Rock & Roll Hall of Fame: Brian Epstein and Andrew Loog Oldham — the Beatles and the Stones. That’s the hard part. The only thing that would tempt me back into management would be lightning striking for a third time — to see James, to see Linda, then to see somebody comparably brilliant, which I occasionally do. But usually they have a manager already.

What’s the last new act that knocked you out?
Ed Sheeran.

Was that just because he looks like he could be your grandson?
That certainly crossed my mind.

As a producer, your records helped define the sound of rock in the ’70s.
The so-called California sound.

Then the zeitgeist shifted.
One became aware of that. Pop music got very electronic, which I loved.

Was there a place for you in that style?
I didn’t consciously try to make records in that style because I don’t think I could have — not as well as they were being made anyway.

What’s a record from the early ’80s that made you think that?
“Sweet Dreams (Are Made of This).” I couldn’t do that.

Back to the ’70s: The doc is filled with pictures of James looking —
Like a movie star. With the cover of “JT,” I finally went all the way and said, “We’re doing the the glamour shot.” Then we did “Flag,” which everyone hated.

With the maritime flag. A truly perverse album cover.
I loved it. James loved it. Everyone thought we were crazy.

How crucial do you think James’ good looks were to his whole proposition?
I don’t know.

Oh, come on.
I really don’t. I mean, how would you gauge that? There’s probably girls who fell in love with him without listening to the record.

I think you just gauged it.
If he was ugly, would he be as big a star? Probably not.

Same applies to Linda, right?
When I first saw Linda, it was stages of realization. Someone said to me, “You’ve got to go down and see this girl at the Bitter End.” I walk in and she’s singing so well — unspeakably good. Then she looks incredibly great — barefoot, short-shorts. Oh, my God, my heart. Then you meet her, and it turns out she’s a remarkably brilliant woman — extremely well read. You just kind of go, “All these things together — how can it be?” It’s the same thing talking about the Beatles: If you cast it like the Spice Girls, you still couldn’t have gotten four to fit together so perfectly.

Did you like the Spice Girls?
Terrific. “Tell me what you want / What you really, really want” — it’s a smash. And yet none of them are particularly good singers, which is kind of the point.

I went to an event not long ago where Paul McCartney played his new album for a small group of fans. It was fascinating to see the spell McCartney casts over people.
He’s had to get used to it — to admit to himself that he can’t meet people who aren’t amazed that they’re meeting him. Even as someone who’s known him off and on for a long time, you still get the wave of: Holy s—.

You’re still amazed to be around him?
Of course. I get it less — I’m ready for it. But you can’t pretend he’s not Paul McCartney. And he’s gotta live with that his whole life.

You grew up a member of the upper crust, I think it’s fair to say.
I don’t think we were that crusty. But upper, probably, yes.

I wondered how that situated you to live and work among artistic types.
If anything, the upper crust have more time to be artistic — less preoccupied with getting a job and making a living. But my parents worked incredibly hard — we weren’t upper crust in the sense of inherited wealth. My father was a doctor, my mother was a professor of music. But I never struggled, to be honest. I had a comfortable allowance, and then I went to school and worked hard. Everyone talks about sharing a flat with a million people, living on borrowed sandwiches — I skipped that phase.

Did that shape you in any meaningful way?
I don’t know. But I think when people do struggle, it becomes a meaningful part of their lives to get away from it. With someone like James, the struggle was a struggle with drugs. Now he says the worst thing about drugs is they’re a complete waste of time — you waste time doing nothing except looking for drugs. And I think that made him anxious to succeed and to be taken seriously.

I’m sure you saw the New York Times’ list of the 30 greatest living American songwriters.
You knew it was gonna be silly. Randy Newman, for God’s sake — you just cannot not include him.

No Neil Diamond either.
Insane.

And no Billy Joel.
[Shrugs].

How’s your health?
High blood pressure, high cholesterol, need to work out more — old man stuff. Other than that and a broken leg, great.

You’re OK with the cane?
It’s a considerable upgrade from the wheelchair. I like the cane — it’s kind of elegant.

What seems scarier: the body going or the mind going?
The mind going. And it is, slightly. I had a stroke, and bits of my brain aren’t quite working right. But compared to other people I know, I’m fine.

We’re at a moment when a lot of foundational rock ’n’ roll figures —
Are dying. It’s all the rage.

What’s it feel like to see your friends and colleagues go?
Better them than me.

Couple more for you: You managed Courtney Love for a spell.
I met her here in Malibu. I also managed Pamela Anderson for a while because she was a neighbor and asked me to help.

What, you put a shingle out?
“Manager for hire.” I’m trying to remember how I first met Courtney — I think Merck Mercuriadis was talking to her about publishing and Kurt stuff. I liked her. Very smart. I like smart women.

She’s easy to work with? Hard to work with?
Impossible to work with.

What’s James Taylor’s best album?
“JT,” maybe.

What’s Linda Ronstadt’s best album?
“Heart Like a Wheel.” With Linda, it’s unfair because they’re so radically different. How do you compare that to a mariachi record and then to Nelson Riddle?

Working with Riddle on those albums must have been a thrill.
He told us all these incredible stories about Frank Sinatra, who he didn’t like although he admired him enormously. It was John David Souther who originally suggested Nelson. Linda had tried doing the album a different way — did some versions with Jerry Wexler and it didn’t work out. So we had a meeting with Nelson: Would he consider doing a couple of arrangements for us? He went, “No.” We said, “What?” He said, “I’ll do an album, though.”

“A World Without Love” was one of eight songs to top the chart in 1964 with “love” in the title. What’s that say about pop music in the mid-’60s?
Same thing it says about pop music of all time: It’s either “I love you” or “She loves you” or “Why don’t you love me?” Weird Al pointed out to me that when you’re looking for a parody of a song, any song that has “love” in the title, substitute “lunch” and it’s funny. “A World Without Lunch” — I mean, who would want to live in such a place?
