In case you missed it, or want to see it again, the video has made its way online, featuring director-star Ben Stiller as Walter Mitty, who constantly disappears into his own fantasy world to escape his humdrum life as a photo manager for Life Magazine. Take a look at the first footage from this adaptation of James Thurber's short story, in theaters nationwide December 25.

Ben Stiller directs and stars in The Secret Life of Walter Mitty, 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 (Kristen Wiig) 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.
