20th Century Fox has issued a new trailer for Ben Stiller’s upcoming adventure fantasy comedy-drama, “The Secret Life of Walter Mitty”. Co-starring Kristen Wiig and Sean Penn, “Walter Mitty” opens in the U.S. on Christmas Day, Variety said.

The film is the second adaptation of James Thurber's 1939 short story of the same name, following the 1947 film.

In the film, a Life magazine worker who lives inside fantasy worlds sets off on a global journey to find a missing picture, which is needed for the final issue of Life.
