Jason Sudeikis and Alison Brie [1] are the stars of Sleeping With Other People, an unconventional romantic comedy from Bachelorette director Leslye Headland. The two play old flames who run into each other after 12 years . . . at a Sex and Love Addicts Anonymous meeting. Acknowledging they both have some pretty series relationship issues, they pledge to stay friends. Obviously, it wouldn't be a romantic comedy if that was the end of the story. Natasha Lyonne, Adam Scott, and Amanda Peet [2] all costar in the film, which debuted at the Sundance Film Festival. It's opening in limited release on Aug. 21!
