Cage channels caveman in animated film 'The Croods'

BERLIN: DreamWorks Animation's new 3D adventure "The Croods" brings the prehistoric age to the 21st century in the form of a dysfunctional family of cave dwellers forced to flee the comforts of home and search out a new life in the unknown.

"Never not be afraid" and "Fear keeps us alive" are the mantras for Grug, the ape-like father voiced by Nicolas Cage and whose first instinct is always to find a cave, block up the entrance and stay there as long as possible.
