Anna Kendrick Busts a Move in a Bikini

Anna Kendrick slipped into a black-and-white-striped bikini top and cutoff denim shorts to film Mike and Dave Need Wedding Dates in Hawaii on Monday. She shared scenes with Aubrey Plaza, who has been in front of the cameras on the islands all week. Zac Efron's also been on Oahu for the project, and he showed off his insanely ripped physique during a rope-swinging excursion over the weekend. The whole group of costars got together for a Memorial Day weekend hike, though we've yet to see Anna and Zac join up on set.
