Brittany Snow and Anna Kendrick in "Pitch Perfect"

Most actresses would find the prospect of filming a nude shower scene especially daunting, but for Pitch Perfect's Anna Kendrick, it was just another day on the job.

Appearing as college freshman Beca, who is heavily recruited to join her school's a cappella group, Up in the Air's Kendrick joked that filming the soapy scene was "the best day of my life."

Ahead of filming, Kendrick, 27, told Anderson Cooper during a Tuesday taping of Anderson Live that she was especially nervous -- even hiding in the corner to change in secret from the cast and crew.

Her tension eased, however, when costar Brittany Snow also stripped down for the exchange, which features Snow's character Chloe ambushing Kendrick's Beca while singing in the shower. "When we started and were disrobing, I was like 'this is awful,' but by the end of the day, it was hot and humid and [I was used to it]," admitted the actress.

Said Kendrick of costar Snow, 26: "At this point, I've got [her body] memorized!"

Kendrick and Snow -- who also appeared on Tuesday's Anderson Live (check local listings for air times) -- join Bridesmaids' Rebel Wilson and Superbad's Christopher Mintz-Plasse in the ensemble comedy, opening nationwide October 5.
