Shaun the Sheep
Shaun the Sheep started as an in-between program, with quick 5 minute sketches to fill space before or after tv programs. Fans took to the adorable sheep immediately, who would often cameo in the Wallace and Gromit movies. He eventually got his own movie where he explores the streets of London after escaping the farm.
Wallace and Gromit
Wallace and Gromit earned a spin-off about a were-rabbit. Weird plot, right? The original short films were so loveable that creators wanted to give the dynamic duo a full feature-length film.
