"The Secret Life of Walter Mitty": Watch the new trailer

A new trailer has arrived for Ben Stiller's adaptation of "The Secret Life of Walter Mitty."

Directed by and starring the "Meet the Parents" actor, the film centers around a daydreamer (Stiller) who escapes his anonymous life by disappearing into fantasies, but must embark on a real-life adventure when a threat approaches.

Kristen Wiig also stars in the film, along with Shirley MacLaine, Adam Scott, Kathryn Hahn and Sean Penn.

The sweeping trailer, set to the Of Monsters and Men song "Dirty Paws," shows Stiller's character emerging from the frozen tundra, watching a black-and-white photo of Penn come to life and jumping from a helicopter into the sea.

Based on the 1939 James Thurber short story of the same name, "The Secret Life of Walter Mitty" is set to arrive in theaters on Christmas Day.
