Poster and US Trailer for 'What's Your Number?'

A low quality version of the international trailer for the Anna Faris/Chris Evans starrer "What's Your Number?" was posted a couple of weeks ago, but now the official US version has made its way online. In the R-rated romantic comedy, based on Karyn Bosnak's novel "Twenty Times a Lady," Faris plays Ally, a woman looks back at the past twenty men she's had relationships with in her life and wonders if one of them might be her one true love. Watch the trailer below and keep an eye out for cameos from Zachary Quinto, Joel McHale, Martin Freeman, Anthony Mackie, Thomas Lennon, and Faris' real-life husband Chris Pratt.
