The Musical Returns to PROOF as a Feature, With Rob Lowe and Gillian Jacobs
A school revenge comedy is giving this year’s PROOF Film Festival a neat opening-week story: a short that won its audience award is coming back as a feature. The American Cinematheque has scheduled Giselle Bonilla’s The Musical for November 5 at Los Feliz 3, with Bonilla and writer-producer Alex Heller due for a Q&A.

The feature stars Will Brill, Rob Lowe and Gillian Jacobs. Its setup puts a frustrated playwright, who also teaches middle-school theatre, opposite a particularly awkward rival: the principal now dating his ex-girlfriend. His chosen weapon is a spectacularly inappropriate school play.
The short came first
According to the Cinematheque’s event listing, The Musical grew from the short that won the 2024 PROOF audience award. This year’s feature is listed as a 2026 release, running 87 minutes, with Blue Harbor Entertainment and Variance Films named as distributors.
That gives the screening more of a hook than a familiar cast alone. Viewers can ask the filmmakers about the distance between a short’s central joke and a feature-length story. The listing establishes that journey; it does not say that winning the festival award guaranteed financing or distribution.
PROOF specialises in proof-of-concept shorts, work that can demonstrate the possibilities of a larger project. For audiences, a finished short still needs to work as a film in its own right. A bigger production somewhere down the line remains a possibility, not something a ticket purchase can promise.
A festival interested in what happens next
The fourth annual edition runs November 5–8. Alongside screenings, its published programme includes a pitch-deck show-and-tell and a financing session on November 7. A conversation about moving from a short to a feature is scheduled for November 8.
Those sessions put practical questions next to the films: how a project is presented, how it might be funded, and what has to change when its running time grows. The Musical supplies a concrete example for that discussion, without suggesting every short on the programme will follow the same route.
Our earlier article on the changing relationship between cinemas and streaming considered where audiences meet films. This festival approaches an earlier stage of that relationship: getting an idea into a form that audiences and potential collaborators can actually watch.
Before heading to Los Feliz
The November 5 screening is listed for 6:30 p.m. local time. General admission is $20 and member admission $15; the event page says those prices include a $2 online booking fee. These are screening-ticket prices, not a quoted price for the whole festival.
All-access badge holders can reserve this event at no additional cost, but the listing specifically requires an advance seat reservation to use that benefit. Badges will not be available for collection that day. Some later industry sessions have separate entry restrictions, so a festival badge and a seat at any particular event should not be treated as interchangeable.
The attraction is a rare chance to see a short-to-feature story come full circle, then hear from the people who made the leap. Attendance and Q&A plans remain subject to the organiser’s current listing.
