A new trailer has been released for the film “The Secret Life of Walter Mitty,” which is based on a short story by writer James Thurber and stars Ben Stiller and Kristen Wiig.

Stiller also directed the film and plays Walter, a worker at Life Magazine who has a crush on Wiig’s character Cheryl and who embarks on a quest to find a negative of an important photo after it goes missing. 

The story, which was released in 1939, was previously adapted as a 1947 movie which starred actor Danny Kate and Virginia Mayo.

Can Syria heal? For many, Step 1 is learning the difficult truth.

The trailer shows some of the daydreams Walter engages in, including one in which he saves Cheryl’s dog and one in which he is a mountain climber.

“Walter” also stars Sean Penn, Shirley MacLaine, Adam Scott, and Patton Oswalt. It’s set to be released Dec. 25.
