TIFF Review: Julianne Moore shines in The Debut

Jesse Eisenberg rose to fame playing awkward nerds, and now as a filmmaker he is giving a specific kind of nerd their due: theater nerds. His third feature film as a writer-director is The Debut, a comedy that borders on farce, set in the world of community theater. Eisenberg writes and directs and appears—and sings—in a small role, but the stars of the show are Julianne Moore and Paul Giamatti, who have two of the best roles of their careers courtesy of Eisenberg’s pen and affectionate lens.

Moore reunites with Eisenberg after starring in his feature directorial debut, When You Finish Saving the World, and is simply spectacular as Mona, a mousy suburban housewife who finds her inner starlet when she lands a small role in a local production of a musical, Nosy Neighbors. (Eisenberg conceived the musical-within-the-film and wrote multiple original songs for it.) Irritable theater director Jerry (Giamatti) has to give Mona the role of an apartment supervisor named Miss Danielle after regional theater star Serena Cherry (Bernadette Peters in a fantastic cameo) bails on the production and no one else auditions (because of Mona).

Mona is, frankly, a terrible actress and she drives Jerry crazy. But as he pushes her to gain any sort of understanding of acting, Mona begins to go full Method for her small part, staying in a run-down motel and finding her inner boss lady. As Mona acts, she gains confidence that spills over into other areas of her life, which in turn loops back into her stage performance, until performing unlocks a door that returns  a piece of herself back to Mona.

The Debut is laugh-out-loud funny—Moore goes on a hilariously filthy tirade as she tries to give life to a simple line that literally brings the house down—and while Eisenberg isn’t afraid of an unlikeable character, the film is so earnestly affectionate toward actors and acting that it never falls into cynicism (though there is some truly weird behavior on display). The Debut sits alongside films like Waiting for Guffman or the Documentary Now! episode “Original Cast Album: Co-Op” for its blatant love of Broadway and actors and acting. It’s very much a love letter from Eisenberg to his own profession, but it’s funny enough to never become maudlin.

It’s also a love letter to Julianne Moore, who is given an all-timer of a role and gives a career-best performance as Mona. Paul Giamatti is also very good, picking out the personal motivations behind Jerry’s irascible façade – but The Debut is Moore’s show. She is dazzling, not least because she has to portray Mona’s transformation from genuinely bad actress to a decently talented one. She’s equally convincing as the inexperienced, unconfident version of Mona as she is the more competent performer who owns (her portion of) the stage—and drives her director crazy for a whole new set of reasons.

She’s just as good as the offstage Mona, who begins dropping family duties in her quest for self-actualization, though Eisenberg doesn’t make a real effort to connect Mona’s brightening star to her deliberately turning down the brightness on her family. The Debut is very much about the stage and performance; Mona’s home life is more context for how and why she became so meek and self-effacing. The film offers no real observations about women achieving success when they are unburdened by their families, it comes through more in Moore’s performance, a connection between Mona adventuring further away from her tidy suburban life in the quest of discovering her inner Miss Danielle, and her visible rise in confidence. The Debut proves that A Real Pain was not a fluke, that Jesse Eisenberg is a filmmaker to watch, and it proves what we already knew, that Julianne Moore truly is one of the best actors working today.

The Debut will play exclusively in theaters from December 11, 2026.
