IFC Films has closed a deal for North American rights to the Jason Sudeikis and Alison Brie romantic comedy Sleeping With Other People, two weeks after its Sundance Film Festival premiere. Leslye Headland (Bachelorette) directed from her own script, with Sudeikis portraying a womanizer and Brie a serial cheater. The characters first meet in college, then rekindle their relationship when they run into each other more than a decade later at a sex addicts meeting. Natasha Lyonne (Orange Is The New Black), Amanda Peet (Togetherness) and Adam Scott (Parks and Recreation) also star. The deal was for above seven figures with a P&A commitment in the seven-figure range. Bidding was heated, with at least half a dozen interested parties at various points. CAA handled the sale. Production companies are Sidney Kimmel Entertainment and Gloria Sanchez Prods. Producers are Sidney Kimmel, Jessica Elbaum, Adam McKay and Will Ferrell; exec producers are Jim Tauber, Carla Hacken, Matt Berenson and Bruce Toll.
