After David Harbour’s exit from the project, Will Arnett has joined the cast of Behemoth!
The Searchlight Pictures production is written and directed by Tony Gilroy. The film’s plot remains under wraps, but a cellist character is known to be central to the story.
Behemoth! stars Pedro Pascal, alongside an ensemble that includes Olivia Wilde, Eva Victor, Matthew Lillard, Margarita Levieva and Alexa Swinton.
David Harbour left the project for personal reasons, with only a limited number of scenes requiring reshoots.
Filming began in October 2025, and the casting change is not expected to impact the film’s release timeline.
