Searchlight Pictures has cast Will Arnett in the upcoming drama Behemoth! after David Harbour exited for personal reasons. Arnett joins a notable ensemble, including Pedro Pascal, Olivia Wilde, and Matthew Lillard, with production having started in late October. The film, directed by Tony Gilroy, centers on a cellist, and Arnett’s recent success in dramatic roles has made him a fitting choice for the project. Reshoots are minimal due to Harbour’s limited scenes, ensuring a smooth transition.
