Angry Kid is a British series of mixed animated/live action shorts made first made by Aardman Animations, then Mr. Morris Productions. It focuses on a secondary school kid, who is rather rude and annoys others. Most of Angry Kid is currently available on YouTube from the official channel or on Atom Films.
However, a pilot was created in 1995 and has not seen an official release in any medium. It was shot on 16-millimetre film and focused on the antics on trying to get Angry Kid to do interesting things.
A copy of the pilot was uploaded to YouTube in 2006 but was taken down around 2007. Since then, a copy has yet to resurface.
