Anna Faris and Chris Evans will star in New Regency's R-rated comedy What's Your Number?, to be directed by Mark Mylod ("Entourage") starting in May.
The film is based on Karyn Bosnak's book "20 Times a Lady," which is described as follows:
How many men does it take to find true love?
Delilah Darling's magic number was supposed to be twenty. She always thought she'd find the perfect guy by the time she'd slept with twenty of them. But when she wakes up naked in her disgusting boss's bed after a drunken night out, she's filled with regret -- and realizes she's hit her self-imposed limit. Unwilling to up her number but unable to imagine a life of celibacy, Delilah does what any girl in her situation would do: she tracks down every man she's ever slept with in a last-ditch effort to make it work with one of them.
Bosnak originally adapted the book for the film. Her script has since been rewritten by Jennifer Crittenden and Gabrielle Allan.
Beau Flynn and Tripp Vinson are producing and 20th Century Fox will distribute.
