Open Season 2 & 3 - Unused/Extented/Alternate Shots
Happy 18th Anniversary to Open Season (2006)'s Russia Release!
From the trailers for both movies, and from some animator's demo reels and etc. Note that I didn't go through every animator's demo reel and etc I could find, but these are just some of these I was able to find.
