"One of the interesting things about this film was that we wanted to create a world that felt prehistoric but was also fresh," says filmmaker Chris Sanders, who's also worked on movies including The Lion King, Aladdin, and Lilo & Stitch. "A huge part of it was going be the animals. Our solution was to take animals and combine them. You could almost imagine, a long time ago, animals were different combinations that maybe, as time went on, they diverged into separate things."
So not only do the creatures that fill The Croods look cool, but they also allow audiences to play a little game called "what is that?" A "ramu" (a ram-emu), a "mousephant" (mouse-elephant, shown here), and a "liyote" (lizard-coyote) are just a few of our favorites.
