Remember back in May when the movie theaters complained about how long trailers were becoming? Well, Ben Stiller has basically given them the finger with this new six-minute trailer for The Secret Life of Walter Mitty. This new look fills in more of the story about Mitty going on a worldwide adventure to track down a lost negative from photographer Sean Penn, in hopes of winning Kristen Wiig's heart. The film opens on Christmas day. Hopefully, Mitty eventually just uses his powerful imagination to imagine sending Penn a negative scanner, so we can instead spend two hours listening to Patton Oswalt work at eHarmony customer service.
