No, no, this isn’t anything official from Valve. These preview images come from a project by Alex Zemke who has taken it upon himself to create his own animated movie about the characters of Portal. Or should I say character? No, let’s include the companion cube, it is after all Chell’s only true friend.
The film is called Companionship and while yes, technically this is a fan project it should be noted Zemke is a professional animator. He’s worked on Disney G-Force and The Smurfs as well as Uncharted 2 & 3. And just look at these images! Something this good can only come from a true labor of love.
Make to check out Zemke’s DeviantArt for updates!
