If you've ever wondered how a family of cavemen can take a photograph, Dreamworks Animation's new trailer for The Croods shows you how it's done. However, it's a much more painful process than today's method. Nicolas Cage voices the patriarch Grug, who leads his family on a journey to find a new home. Along the way, they run into Guy (Ryan Reynolds) a free thinker whose bold ideas are too much for Grug to digest. Take a look at the latest footage from this animated comedy, also starring Catherine Keener, Emma Stone, Clark Duke, and Cloris Leachman.
