The Debut

Mona Friedman (Julianne Moore) has somehow become an offstage character even within her own life. She’s a Nineties New Jersey housewife turned mousewife, looking after her husband Howard (Patrick Fabian) and their kids Matty (Jonah Diamand) and Maya (Becca Suskauer), who barely acknowledge her existence. Perhaps that’s why she auditions for an am-dram production of musical Nosy Neighbors. You can tell she doesn’t really think she’ll be cast, but for a moment – and it is a brief one – she gets to be the centre of attention as she tries out.

She doesn’t get the part… until a twist of fate means she does. The sort of twist of fate, that like much of Jesse Eisenberg’s knowing and playful film, could itself be a plot beat in a musical. Nosy Neighbors is being directed by Gerry (Paul Giamatti) – “He’s not here to be your friend,” Mona is told. Mona is to play Miss Danielle, the superintendent of the building, a supporting character with a never-say-die solo number who gets to deliver the less-than-immortal line: “Rent’s due!”.

Moore withdraws herself into Mona, her buttoned up, delicate cardigans an indicator of how she has been taught to live her life as an exercise in blending in and keeping her voice down. Gerry aims to change all that, calling upon her to dig deep within herself to find the emotions she can channel for Miss Danielle. Gerry, pitched just right by Giamatti as a ‘big’ character who nevertheless has his own fragilities, will soon regret what he wished for as Moore slowly opens the floodgates and Mona begins turning Miss Danielle into her life’s cause.

Eisenberg’s obvious love of amateur dramatics provides The Debut with a foundation that feels akin to a warm hug. Even before Mona really starts becoming Little Miss Method Actor, she feels the benefit of people who are enjoying coming together to create something. There’s a welcoming happiness to the group, complete with bananas to keep up those vitamin levels, and a belief that they can put on a show to be reckoned with. Eisenberg, who pops up in a sweet supporting role himself, also wrote the music and he manages to keep the Nosy Neighbor’s numbers in the realm of pastiche rather than parody, gently highlighting some of the well known clichés while acknowledging why they are so effective.

Mona’s attempts to get in touch with the gritty life of Miss Danielle are often hilarious – not least the chain smoking she adopts without ever actually lighting a cigarette – but there’s also a real pathos to this woman who suddenly finds herself given permission to transform her life, even if it’s just in pursuit of a two-minute moment in the spotlight. Once the fire of enthusiasm is lit inside her, she begins taking on Gerry over the believability of her character, but her desire holds an undernote of desperation that could mean she is the one who gets burned. There’s a slight level of unreality to all of it, a heightened perspective brought by Mona’s viewpoint that makes everything in her real world, especially a skid row apartment block she frequents feel as though it could have been trucked in from an Off Broadway stage.

Eisenberg, in a way, serves up a two-for-one deal here, the musical itself with its cheerfully predictable happy ending – so long as Mona plays along – plus the wraparound character study, which while, knowingly, holding a certain number of familiar plot beats is breezily hilarious and just spiky enough to keep us guessing as to what might happen before the curtain falls.
