The Behemoth Pedro Pascal trailer has introduced audiences to Tony Gilroy’s first directed feature in 14 years — a music drama about a gifted cellist who trades life on the road for a new career creating music for the movies. Searchlight Pictures released the official trailer on October 28, 2026, ahead of a cinema release on December 4, 2026, according to GeekTyrant, QNC News and Attitude, which all reported the trailer and date.
Pascal plays Alex Serian, a gifted cellist from a family of musicians who returns home to Los Angeles after spending 20 years on the road, according to QNC News and GeekTyrant. The trailer opens with Alex at work on a major Hollywood production operating under the secret title Behemoth! — the same title as Gilroy’s film — and follows him into a story about family, artistic identity and the power of music, according to Hollywood Box and GeekTyrant.
Nine composers, one fictional film world
One of the film’s most unusual features is its music. Gilroy recruited nine composers, billed as the Behemoth! Collective, to build the fictional scores heard in the film: Michael Abels, Emily Bear, Lukas Frank, Michael Giacchino, James Newton Howard, Henry Jackman, Nami Melumad, Brandon Roberts and Alan Silvestri, according to QNC News and GeekTyrant. Each composer tackled a separate fictional film score, giving the movie-within-a-movie its own musical identity.
The ensemble cast alongside Pascal includes Olivia Wilde, Eva Victor, Alexa Swinton, Kaya Ralls, Erik Griffin, Jobeth Williams, Margarita Levieva, Hank Azaria and Will Arnett, according to GeekTyrant, with Hypebeast also noting Matthew Lillard in the cast. Gilroy wrote and directed the film, with John Gilroy and Sanne Wohlenberg producing, according to GeekTyrant and QNC News.
A festival launch before awards season
Behemoth! premiered at the 2026 New York Film Festival earlier in October, where it was the Centerpiece selection, and also screened in London, according to QNC News and GeekTyrant. Attitude reported that the trailer passed five million views in less than 24 hours, with one brief shirtless moment drawing particular attention from fans online — a reminder of Pascal’s pulling power, even for a film about classical music.
Searchlight will release the film in select US cinemas on December 4, placing it in the heart of awards season, according to QNC News. For Gilroy, best known as the creator of Andor and the writer-director of Michael Clayton, it is a return to directing after The Bourne Legacy in 2012 — and a gamble that audiences will follow a story where the loudest drama happens on a scoring stage.
