Ben Stiller directs himself in Fox’s Christmas release “The Secret Life of Walter Mitty.”

The film, which co-stars Kristin Wiig, Adam Scott and Shirley MacLaine, follows a shy man who, while often daydreaming up fantastical scenarios to escape his mundane life, actually embarks on a global journey to discover himself. Pic is based on the classic short story by James Thurber.

Fox was extremely enthusiastic about the film during CinemaCon in April, when the studio screened nearly 20 minutes for exhibitors.

Here’s the film’s first trailer, featuring the song “Dirty Paws” from Icelandic band Of Monsters and Men. (Interesting side note: a good chunk of “Mitty” was filmed in Iceland.)
