Deadline reports Rebel Wilson has joined the cast of Night at the Museum 3 (a.k.a. Night at the Museum but the M is a rotated 3). She'll play the night guard at the British museum that gets nighted. She will be joining Ben Stiller, Robin Williams, Ricky Gervais, Steve Coogan, and Dan Stevens. The film is aiming for a Christmas 2014 release. That last one grossed $413 million worldwide, which would make it probably America's most successful museum. USA! USA! USA!
