On the final night of filming, Rebel Wilson was in the middle of a fight scene, and the gun used in the scene accidentally got whacked across the front of her face. Her nose began bleeding profusely. She had to leave the set, and was taken by ambulance to be treated by a plastic surgeon.
Rebel Wilson did most of her own stunts in the film. However, because of her fear of heights, Wilson declined to perform the stunt where Wilson's character Sam jumps through a window and crashes through the top of van.
Rebel Wilson and Anna Camp had previously co-starred together in Voices (2012), Pitch Perfect 2 (2015), and Pitch Perfect 3 (2017). Plus, Gigi Zumbado appeared in Pitch Perfect 2 (2015) as a member of the Cantasticos, one of the a cappella groups that competed against the Barden Bellas in the climactic World Finals.
