The Debut Review: TIFF 2026

A rare thing happened during the pre-TIFF press screening of The Debut . The theatre full of critics—a usually quiet, polite, and reserved bunch of Torontonians—erupted into enthusiastic applause for Julianne Moore after she delivered a knockout, gonzo monologue that ran the gamut of emotions with jaw-dropping bravery. Reports from colleagues said that a similar feat happened at the same moment during the afternoon press screening later that day. The mid-movie applause repeated news from the film’s Telluride premiere over Labour Day weekend. Three times marks a charm for Moore. Her performance in The Debut is easily the best acting coup of the year and one of those feats destined for the history books. Which says a lot given Moore’s résum é.

Moore’s performance as Mona, a timid housewife who auditions for a role in community theatre and miraculously gets the part (because nobody else tried out) shows how an Oscar winning veteran like manages to surprise decades into her career. At the risk of giving her a back-handed compliment, it’s a performance that I frankly didn’t know Moore could give. Comedy, simply put, hasn’t been Moore’s strong suit. Her track record with shattering dramas bats better with Far From Heaven or Boogie Nights than it does with larks like Evolution or The Laws of Attraction . That creative leap makes her turn as Mona so fearlessly rewarding. In this story about an actress pushing herself beyond her limits and surrendering to her character, Moore bravely meets the challenge by taking herself to boundaries seemingly unexplored.

Mona barely cracks a whisper when she fumbles her audition for the show. Writer/director Jesse Eisenberg hilariously underscores the extent to which Mona is out of her depth trying out for a musical, even a community theatre bit part. He precedes her audition with a musical number by Broadway legend Bernadette Peters belting out the part. It’s a swell show tune called “This City May Have Chewed Me Up (But Hasn’t Spit Me Out).” The droll original number highlights the crappy New York apartments with bathtubs in the kitchen that populate the building of which Miss Danielle is the superintendent. Peters, playing local community theatre starlet Serena Cherry, kills it with dramatic levels and comedic punches. Moore, never really known for signing, squeaks through the song until the play’s director, Jerry ( Paul Giamatti ), cuts her off. He’s seen enough.

Rejection nags at Mona. She clearly wants the part. It’s not so much a need to stretch her dramatic chops as it is to fill the void of suburban life. Her twins are graduating, her husband prefers to shit in peace, and their friends have bad taste in restaurants and cocktails. She needs Miss Danielle badly.

Opportunity knocks when Cherry drops out and leaves Jerry with no alternative but to call Mona. So begins a trial by fire as Jerry’s taskmaster ways sadistically prime his ingénue for the stage.

The perfectionist director takes his job in community theatre far too seriously. He relishes putting his actors through hell. As Mona flubs lines and deflates the energy of the musical, Nosy Neighbors , with her flat, timid delivery, Jerry strikes. He makes an example out of Mona to teach everyone how to burrow inside their characters.

Giamatti provides a wicked foil for Moore. It’s hard to imagine anyone else in this part as he’s mastered the appeal of these quick-witted curmudgeons without ever making it seem that he’s repeating himself. Giamatti and Moore ferociously attack the material as Jerry pushes Mona to find Miss Danielle. The duo has lots of fun undergoing acting exercises, and there’s a deliciously meta nature to this observation of the acting process as Jerry demands more, more, and more and Mona learns how fun it can be to plunge into the terrifying depths of a character.

Mona’s acting spark explodes in the bravura centrepiece scene as Jerry breaks her shell. Moore gets the aforementioned monologue as she imagines why the city chewed Mona up and why being a building supervisor gets her off. Her anxiety mounts as she imagines delinquent tenants forcing her to live on the street, eat rats, and contract plague. It’s a breathless feat of acting as Moore escalates Mona’s feverishness, seemingly unlocking decades of repressed feelings. As Giamatti eggs her on, seemingly pulling with all his might to extract an actor from Mona’s bowels, Moore goes all in. It’s an all gas, no brakes coup that may be the finest acting feat this year.

The Debut has the acting bug in its bones as the third feature from Jesse Eisenberg as writer/ director. (He also has a smaller role here as a member of the theatre ensemble who’s unlucky in love.) After When You Finish Saving the World and A Real Pain , The Debut marks an extraordinary leap forward for Eisenberg in terms of the scope of his filmmaking and his audacity to be original. He display a great eye for staging and framing Mona to accentuate her fish-out-of-water status, always finding humour in her discomfort without punching her down for trying.

Featuring seven original songs and the unabashed sincerity of musical theatre as an endearing entry point, The Debut hooks audiences with the Waiting for Guffman charm of the theatre scene and yet morphs into something deep and dark. Eisenberg handles tricky tonal shifts as Mona becomes consumed by her drive to deliver a real performance, forgetting that the theatre isn’t supposed to provide a literal escape from the life she desperately needs to flee. There are echoes of Black Swan , The Red Shoes , and even Inland Empire as Mona spirals and tests the fine line began between committing and needing to be committed.

Moore’s locked-in performance carries Mona’s discovery of Miss Danielle through its wildest moments. Yet Eisenberg’s trust in Moore to follow Mona down the rabbit hole takes The Debut to comedic highs that make one see a Hollywood icon anew. It’s the kind of movie that only an actor could make, too, as it trusts actors of this calibre chew the parts up and spit them out without ever eating the scenery. The Debut deserves a standing ovation. It’s a sure-fire contender for “best of the fest” and, quite possibly, the year.
