Three years after Grown Ups, Adam Sandler is back as the eternally adolescent Lenny, who’s moved with his family from the big city to his childhood hometown. Set on a single summer day, the sequel — Sandler’s first ever — once again follows the escapades of Lenny and his band of arrested-development pals (played by Chris Rock, Kevin James, and David Spade). One such adventure involves returning to a quarry the guys frequented as kids, where they run into a frat boy played by…Twilight‘s Taylor Lautner. ”As adults they go back there, but these frat guys have taken over,” says director Dennis Dugan. ”There’s a big confrontation.” And a big, nude leap off a cliff.
