Jason Sudeikis and Alison Brie 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 all costar in the film, which debuted at the Sundance Film Festival. It's opening in limited release on Aug. 21!
