Originally, The CROODS was not a story about a literal family, but a community, a tribe. Each member of the tribe had a duty, depending on one another during a hunt or within the cave...etc. Chris and Kirk were also playing with the idea that the Croods would be a musical society. Even when hunting, sound could be their tool. The story was always set in a volatile, prehistoric time between time. An ever-changing, chaotic, world. So the question of what characters would look like in this strange, non-recorded time turned into an exciting challenge. Would they just look like us today? Or would they be some "crude" intermediate version of a human. The initial drive was to go away from literal human and make a more abstract statement to reflect the story's setting. We were referencing nature (Rocks, trees, water) as well as ancient cave paintings and sculpture as inspiration for the characters. Also, in the original story there was a neighboring tribe of even less evolved and more animalistic creatures called the BOGS. The Bogs were supposed to be both stupid and terrifying. The Bogs wanted the Crood's cave and were a constant threat. Things would change as the story would change, but here is a small sample of my first explorations for both the CROODS and the BOGS.
