Kristen Wiig: 'Secret Life of Walter Mitty' Set!

Kristen Wiig hangs out of a police car as she films scenes for her new flick The Secret Life of Walter Mitty on Saturday (May 26) in New York City.

The film is about a timid magazine photo manager (Ben Stiller) who lives life vicariously through daydreams and embarks on a true-life adventure when a negative goes missing.

Ben is not only starring in the film, but is also directing! Sean Penn, Parks and Recreation‘s Adam Scott, and Shirley MacLaine also star.

The Secret Life of Walter Mitty is slated for a 2013 release.
