Jennifer Aniston has signed on to costar with Adam Sandler in The Pretend Wife. Dennis Dugan is expected to direct the romantic comedy but much is being kept under wraps about this project, including the plot. All we know is that the original title was Holiday in Hawaii. It’s unclear whether a fat guy will fall down or if Rob Schneider will play a weird ethnic dude. We’re not even sure if someone will be injured in a testicle-hitting mishap. But I vow that once I know, you will know. (THR)
