Searchlight Pictures has moved swiftly following the David Harbour Behemoth exit, bringing Will Arnett on board to replace him in the upcoming film Behemoth!, directed by Tony Gilroy. The casting change comes after Harbour departed for personal reasons, with production still on track to wrap within weeks and the project’s ensemble remaining strong.
Studio Responds Fast to Harbour’s Departure
After Harbour’s exit, Searchlight Pictures wasted no time securing Arnett for the role alongside Pedro Pascal. The cast also features Olivia Wilde, Eva Victor, Matthew Lillard, Margarita Levieva, and Alexa Swinton. The studio’s decision reflects confidence in a smooth transition, as insiders report minimal disruption due to Harbour’s short filming schedule, dictated by his commitments to Stranger Things press activities.
Production Timeline and Plot Details Remain Confidential
Behemoth! began filming in late October, and according to industry insiders, reshoots needed to accommodate Arnett’s arrival are expected to be minimal. The overall timeline for completion is not anticipated to change. Although Searchlight has not released a full synopsis, the story is confirmed to revolve around a cellist. Tony Gilroy wrote the script and also serves as producer, with Sanne Wohlenberg and John Gilroy—his collaborators from Andor—joining the production team.
Will Arnett Embraces Dramatic Roles
Will Arnett’s addition to Behemoth! reflects a trend in his career toward more dramatic work, following acclaim for his leading role in the Searchlight film Is This Thing On?, released over the holidays and directed by Bradley Cooper. That dramedy showcased a new side of Arnett, marking his strongest critical reception yet. Industry sources indicated that after Harbour departed, Arnett was seen as the leading choice for the part in Behemoth!, thanks in part to his recent performance and growing dramatic range.
Looking Ahead for Behemoth!
The ensemble cast led by Arnett and Pascal, combined with Tony Gilroy’s direction and a tightly kept storyline, is setting high expectations for Behemoth!. With the transition nearly complete and production moving forward efficiently, attention now turns to how Arnett’s presence will shape the film and what impact his evolving career will have on this high-profile project.
