Here are some of my favorite stop-motion films. I have a lot, but these are a few I've been thinking about lately. Enjoy!
The Potato Hunter by Tim Hittle
Brother by Adam Elliot
I love everything Adam Elliot does, so check out his other films as well: Uncle, Cousin, and also Harvey Krumpet. He also has a feature coming out soon, Mary andMax.
Wallace and Gromit: A Grand Day Out by Nick Park(Aardman)
The Neverhood by Doug TenNapel
This is one of the coolest games ever.
