Here's a fun clip from Ben Stiller's upcoming film The Secret Life of Walter Mitty. It features the title character on one of his adventures as he jumps out of a helicopter and into the freezing cold ocean. There he ends up being attacked by a shark, which is always a good time. If you haven't tried it yet, you definitely should. It's quite the adrenaline rush. The amazing-looking imaginative adventure film comes out on December 25th! Enjoy the clip thanks to Empire!
