Stiller’s Mitty starts to live in the latest trailer reveal of “The Secret Life of Walter Mitty,” a modern-day dreamer photo editor whose dreams turned into reality when he realized the peril of losing his job is about to materialize. Taking on the impossible and unimaginable journey of his life, Mitty steps out of his own private realm to search for a famous photographer’s (Sean Penn) missing negative.
“The Secret Life of Walter Mitty” offered a rare chance for Ben Stiller to look at a touchstone American tale afresh, from new times. Way back in high school, he first encountered Thurber’s story – a story that almost as soon as it had been published in The New Yorker began making an impact that belied its ultra-brief length. It inspired a beloved 1940s screen comedy, numerous theatre works, and sealed the phrase “he’s a Walter Mitty” into the popular lexicon, referring to anyone who throws more energy into diverting daydreams than into real life.
Now, Stiller saw a chance to take Thurber’s endlessly escapist character into the full-scale complexity of our social networking, down-sizing, re-tooling times– and to push his story 
further, comedically, dramatically and cinematically, bringing the full visual spectacle of modern filmmaking to the mix.
“The Secret Life of Walter Mitty” will open January 2014 in theaters nationwide from 20th Century Fox to be distributed by Warner Bros.
