Crood Awakening

As part of Aardman Animation's "five-picture deal" with DreamWorks Animation, an animated film called Crood Awakening was in the early works at Aardman. The film was written by John Cleese and Kirk DeMicco.

Plot
The premise of the film would've been loosely based on the Roald Dahl book The Twits but set in the Stone Age.

Why It Was Cancelled

 * 1) Aardman and DreamWorks separated in 2007 after the box office failure of Flushed Away.

Results

 * Dreamworks made an animated movie set in the Stone Age: DreamWorks in 2013 with The Croods (where Cleese and DeMicco were heavily involved). 5 years Later, Aardman made Early Man in 2018.
