Chewie

It's mostly (if not all) in English anyway, as I recall. I can't find the one I watched, but here's a link gcinee posted on dailymo:

This movie tells a believable story about believable characters which made the ending richly rewarding. It does move slowly at times, but I found it worth the wait.

Does anyone know the name of the actor who plays Wut (the one obsessed with Chai)?

Disturbing, poorly executed, and completely unsatisfying.
