American Classic is a hidden gem, in more ways than one. It’s hidden because it’s on MGM+, a stand-alone streaming service that, let’s face it, most people don’t have. But MGM+ is available without subscription for a seven-day free trial, on its website or through Prime Video and Roku. And you should find and watch American Classic, because it’s an absolutely charming and wonderful TV jewel.

Charming, in the way it brings small towns and ordinary people to life, as in Northern Exposure. Wonderful, in the way it reflects the joys of local theater productions, as in Slings & Arrows, and the American Playhouse production of Kurt Vonnegut’s Who Am I This Time?

The creators of American Classic are Michael Hoffman and Bob Martin. Martin co-wrote and co-created Slings & Arrows, so that comparison comes easily. And back in the early 1980s, Who Am I This Time? was about people who transformed onstage from ordinary citizens into extraordinary performers. It’s a conceit that works only if you have brilliant actors to bring it to life convincingly. That American Playhouse production had two young actors — Christopher Walken and Susan Sarandon — so yes, it worked. And American Classic, with its mix of veteran and young actors, does, too.

American Classic begins with Kevin Kline, as Shakespearean actor Richard Bean, confronting a New York Times drama critic about his negative opening-night review of Richard’s King Lear. The next day, Richard’s agent, played by Tony Shalhoub, calls Richard in to tell him his tantrum was captured by cellphone and went viral, and that he has to lay low for a while.

Richard returns home to the small town of Millersburg, Pa., where his parents ran a local theater. Almost everyone we meet is a treasure. His father, who has bouts of dementia, is played by Len Cariou, who starred on Broadway in Sweeney Todd. Richard’s brother, Jon, is played by Jon Tenney of The Closer, and his wife, Kristen, is played by the great Laura Linney, from Ozark and John Adams.

Things get even more complicated because the old theater is now a dinner theater, filling its schedule with performances by touring regional companies. Its survival is at risk, so Richard decides to save the theater by mounting a new production of Thornton Wilder’s Our Town, casting the local small-town residents to play … local small-town residents.

Miranda, Richard’s college-bound niece, continues the family theatrical tradition — and Nell Verlaque, the young actress who plays her, has a breakout role here. She’s terrific — funny, touching, totally natural. And when she takes the stage as Emily in Our Town, she’s heart-wrenching. Playwright Wilder is served magnificently here — and so is William Shakespeare, whose works and words Kline tackles in more than one inspirational scene in this series.

I don’t want to reveal too much about the conflicts, and surprises, in American Classic, but please trust me: The more episodes you watch, the better it gets. The characters evolve, and go in unexpected directions and pairings. Kline’s Richard starts out thinking about only himself, but ends up just the opposite. And if, as Shakespeare wrote, the play’s the thing, the thing here is, the plays we see, and the soliloquies we hear, are spellbinding.

And there’s plenty of fun to be had outside the classics in American Classic. The table reads are the most delightful since the ones in Only Murders in the Building. The dinner-table arguments are the most explosive since the ones in The Bear. Some scenes are take-your-breath-away dramatic. Others are infectiously silly, as when Richard works with a cast member forced upon him by the angel of this new Our Town production.

Take the effort to find, and watch, American Classic. It’ll remind you why, when it’s this good, it’s easy to love the theater. And television.
