Don’t stop me if you’ve heard this one before, since I’m admittedly something of a broken record on the subject, but I very much prefer Marvel’s television series, which tend to be fleet, original and unpredictable, to its movies, which tend not to be. “Loki,” “Ms. Marvel,” “Moon Knight,” “Echo,” “WandaVision” and its spinoff “Agatha All Along” — all (among others) are worth watching, even the ones that are dumped after a season.

Developing longer stories with less money, the TV shows makers need to be inventive, creative with their resources, so they invest in characters and ideas rather than special effects and action. They focus on secondary or ensemble figures who would never be given a theatrical feature of their own to carry, are particular about culture and family and place, and are often less contingent on the Marvel Cinematic Universe, with its phases and stages, its crossovers and cross-promotions and long-range marketing plans. At once higher concept and more grounded than the movies, they’re interesting on their own, to the point where, when they finally hitch on to the Marvel multi-mega-serial train, I find them disappointing.

“Wonder Man,” whose eight episodes premiere all at once Tuesday on Disney+, is perhaps the most grounded of these series. Created by Destin Daniel Cretton (“Shang-Chi and the Legend of the Ten Rings”) and Andrew Guest (who has written for “Community” and “Brooklyn Nine-Nine”), the series is a (generally) sweet, disarming tale of actors in Hollywood, tricked up with picture-business details that you don’t need to be au fait with the MCU to appreciate. There are things it might be helpful to know, but you can work out everything that matters through context. (Locals will enjoy playing Spot the Locations.)

Yahya Abdul-Mateen II plays Simon Williams, who as a child became a fan of a B-movie superhero called Wonder Man — not a “real” superhero, in this reality, merely a fiction. Now in his 30s, he’s a struggling actor in Hollywood, good enough to land a small part in an “American Horror Story” episode, but not clever enough to keep from slowing down the production with questions and suggestions when all he needs to do is deliver a couple of lines before a monster bites his head off. He loses the part and a girlfriend directly afterward.

Taking in a revival house matinee of “Midnight Cowboy,” he meets Trevor Slattery (Ben Kingsley), who is back from having played the Mandarin — that is, he acted the part of a terrorist called the Mandarin, believing it was just a job — in “Iron Man 3” and providing appealing comedy relief in “Shang-Chi and the Legend of the Ten Rings.” The character here is more fleshed out, something of a mess (but 13 years sober, he likes to point out), serious but not a joke. Before it all went wrong, Trevor played King Lear (in Croydon), appeared in “Coronation Street” and in a movie with Glenda Jackson, was off-off-off Broadway in “The Skin Our Teeth” and briefly had the lead in a hospital show with Joe Pantoliano, who’s very funny playing himself.

Slattery tells Simon that European art director Von Kovak (Zlatko Burić) is rebooting Wonder Man, a role Simon feels born to play. He makes an end run around his unconvinced agent, Janelle (X Mayo), and wheedles an audition — where he again meets Trevor, auditioning for Barnaby, Wonder Man’s pal, or sidekick or something. There are wheels behind wheels in this setup, some of which could use a little grease, but for most of the series they do their squeaking off to the side. It’s a love story, above all — “Midnight Cowboy,” not an accidental choice, is more of a touchstone than any Marvel movie.

Simon does have powers — things shake, break or explode around him when he’s upset, and his strength can become super in a tight spot — which puts him in the sights of the Department of Damage Control, embodied by Arian Moayed as P. Cleary, who would like to contain him. But he struggles to keep them secret, especially in light of something called the Doorman Clause — its history established in a sidebar episode, a cautionary Hollywood fable with Josh Gad as himself — which prohibits anyone with super powers from working in film or television, all Simon lives for.

There is little in the way of action, and you won’t miss it. The fate of the world is never in question, but a callback for a second audition means everything. The only costumed characters are actors playing costumed characters; the only villains, apart from the bureaucracy that seeks to bring him in, are Simon’s own self-doubt and temper. As things progress, Trevor will become a mentor to Simon. As is common in stories of love and friendship, a betrayal will be revealed, but if you have seen even a few such stories, you know how that’s going to go, and will be glad it does.

Whether discussing acting techniques or the traffic they’re stuck in on Hollywood Boulevard (Trevor: “Probably the Hollywood Bowl.” Simon: “It’s too late for the Bowl.” Trevor: “It’s usually the Bowl. I remember seeing Cher there once — breathtaking. Chaka Khan, now there’s a woman”), Abdul-Mateen and Kingsley work well together; their energies are complementary, laid back and loose versus worked up and tight and, of course, each will have something to teach one another about who they are and who they could be. I was genuinely anxious for them, as friends, more so than just wondering how such and such a superhero (or team) might defeat such and such a supervillain (or team).

“Our ideas about heroes and gods, they only get in the way,” says Von Kovak, putting a room of hopeful actors through their paces, and essentially speaking for the series he’s in. “Too difficult to comprehend them. Let’s find the human underneath.”
