Big Buck Bunny is an animated film created using Blender, and was released under a Creative Commons Attribution 3.0 license by the Peach open source animation project.
The film is a follow-up to the much downloaded "Elephants Dream," and was sponsored by the Blender Foundation, the initiators of both the open source projects.
The hyper violent storyline of the film revolves around Big Buck Bunny, a good natured, obese "wabbit," who is harassed by three pesky rodents. The film has a less-than-subtle nod to some of Arnold Schwarzenegger’s action scenes in the first Predator movie.
You can download the movie in various file formats (including full HD with 5.1 channel sound), for absolutely free.
