It’s coming to theaters on December 25th and “The Secret Life of Walter Mitty” has just unveiled the first teaser trailer.

The sure-to-be-awesome flick boasts a killer cast that includes Sean Penn, Kristen Wiig, Adam Scott, Kathryn Hahn, and Shirley MacLaine, making for a well-rounded and varied ensemble.

And with Ben Stiller serving as director, “The Secret Life of Walter Mitty” already has some pretty high expectations to live up to.

Per the synopsis, “The film is based on James Thurber's classic story of a day-dreamer who escapes his anonymous life by disappearing into a world of fantasies filled with heroism, romance and action. When his job along with that of his co-worker are threatened, Walter takes action in the real world embarking on a global journey that turns into an adventure more extraordinary than anything he could have ever imagined.”
