Pitch Perfect (2012)

The singalong pick for a group that would rather perform than just watch. Anna Kendrick's Beca is a reluctant freshman pulled into a college a cappella group, and the film is at its best in the riff-off, an empty-pool battle where the groups trade songs on the fly. Rebel Wilson's Fat Amy steals most of the scenes she is in, and Kendrick's "Cups" audition is the moment people still reach for a plastic cup to copy. The competition plot is predictable, but nobody puts this on for the plot.
