What's Your Number, a romantic comedy about a woman who freaks out after learning she's had 20 sexual partners, and decides to find true love with one of the former flames rather than sleep with number 21. Chris Evans will be joining her in the comedy, playing the role of womanizing next-door-neighbor who helps her set out to track down the ex-boyfriends. The movie is based on Karyn Bosnak's novel 20 Times A Lady.
