"Upcoming Portal Animated Film Has An Awesome Pixar Look"
Though still a work in progress, the still frame (which comes from Alex Zemke) looks quite promising.
Zemke, who is working on the animated short titled Companionship, is a professional animator who has worked on various Sony properties such as Uncharted 2 and 3, as well as the The Smurfs Movie.
Companionship, which is a “tale of love, loss and cubes”, sounds like a project that Zemke is quite passionate about. Though there is no telling when the completion date will be, you can check out Zemke’s Deviant Art page for more stills from the project.
