What happens when a blind date goes really well? Or, what if it seems like it is, but then you discover you're actually on a date with someone who is not who you thought they were? Hey, it's happened to everyone! Somehow, this trailer for the romcom "Man Up" makes it seem sweet and funny.

Lake Bell plays a British woman named Nancy who has a cynical outlook on love and cheesy self-help books. She's a cool lady who's giving dating and "putting yourself out there" the old college try, so when she's mistaken by Jack (Simon Pegg) for his blind date, she decides to roll with it. What ensues is... a really great date! Eventually, Nancy has to fess up that she's not the nubile 24-year-old Jack thought he was meeting, and Jack is understandably upset that she lied. (Of course, Jack is a 40-year-old divorcee, so maybe he should chill out with trying to date 24-year-old women. Just saying.) Hijinks ensue, but will love triumph?

"Man Up" opens in the U.K. on May 29. The movie will have its United States premiere at the Tribeca Film Festival in April.
