Anna Faris’ R-rated comedy What’s Your Number? is assembling quite a supporting cast to play her slew of ex-boyfriends. Saturday Night Live’s Andy Samberg is attached and an offer is out to Star Trek’s Zachary Quinto to play two of the men she revisits in her quest to find love. The New Regency film is based on Karyn Bosnak’s book 20 Times a Lady and tracks Faris’ character Delilah, who upon sleeping with her 20th guy realizes that it’s too many and she must have missed her Mr. Right along the way. Chris Evans is already attached to play her womanizing next door neighbor.

New Regency is producing and filming is scheduled to begin in May, plenty of time for Evan to shoot before going off to be Captain America. Mark Mylod (Entourage) will helm.
