The series is produced by an animation studio called Aardman Animations (originally founded in 1972) and they're based out of Bristol which creates both stop motion and clay animations. As of 2020 their studio have gone on to earn over a whopping $1.1 billion dollars worldwide, with an average of $134 million dollars per film. We like to think they knocked it out of the park back in 1989 with their first Wallace & Gromit film and have created amazing animations ever since.
