The Croods trailer.
A new animated movie from DreamWorks… this one about a family of cavemen (and cavewomen/girls) who lose the cave where they have lived all their lives, and have to go off into a very strange world to make their way. Not sure if half these odd animals actually existed in prehistoric times (and I know there were some very strange and large hyper-mammals – most of which we exterminated along the way), but heck, how real were the Flintstones, right?
