Searchlight Pictures has released the first trailer for “Behemoth!,” a music-focused drama written and directed by Tony Gilroy and starring Pedro Pascal. Multiple outlets describe Pascal as Alex Serian, a classically trained cellist from a Los Angeles musical family who returns home after about 20 years “on the road,” beginning a new chapter tied to music composition. The film is framed around the role of music in Hollywood, with coverage emphasizing its connection to the film-scoring world. The trailer previews the movie’s premise as a story centered on Serian’s craft and family background, alongside other characters including Olivia Wilde and Eva Victor. Will Arnett is also reported as part of the cast, with additional ensemble performers named across the reporting. Some sources add that the score features a group referred to as “The Behemoth! Collective,” made up of multiple composers connected to film music. Searchlight sets a theatrical release date of December 4, 2026, positioning the film during the awards-season period. Overall, the trailer and casting details point to a drama blending classical cello performance with behind-the-scenes perspectives on composing for movies.
