Rebel Wilson was recognized for her performance in the comedy film Bridesmaids upon auditioning for the role of Fat Amy, which she won instantly. Moore recalled Wilson singing Lady Gaga's "The Edge of Glory" while beating "on her chest with her fists. " He said, "I didn't even hear the end of the song because I was laughing so hard. There's this beautiful openness to the way Rebel approaches everything, and that's what works great for the character. She's fearless. " Adam DeVine was personally chosen by Banks and Handelman for the role of Bumper after they saw him on the television series Workaholics. Banks confessed that she and her husband are "big Workaholics fans," and after watching one night during the film's casting, they saw DeVine and "immediately thought" he would be a good choice for Bumper. He initially declined because he was not a singer. DeVine eventually surprised Banks and Handelman with his vocal skills. Anna Camp was chosen for the role of Aubrey. Producer Max Handelman said, "Elizabeth and I were huge fans of Anna's from True Blood. Aubrey is set up as the antagonist for Beca, and Beca's already a bit hard-edged, so it was so important to find an actress who could play Aubrey as someone who could marshal the crazy but also was sympathetic.
