Cage will play the role of Crug. He cautiously leads his family after an earthquake destroys their home. While attempting to get through this dangerous and unfamiliar world, Crug comes up against Reynolds' nomad, who charms Crug's clan, especially his daughter, with his progressive ways of thinking.

Kirk DeMicco (Space Chimps) will co-write and direct this project with Chris Sanders (Lilo & Stitch).

The Croods was developed by DeMicco and John Cleese. It will be released March 30, 2012, in stereoscopic 3D.
