4x75 - Mr. Bean: The Animated Series

While Mr. Bean is taking photos of wildlife including the foxes (from the episode "In the Wild") he sees big footprints which belong to a dinosaur. He runs away from it until he gets an idea to take a photo of it, hoping he'll become famous. However, the dinosaur turns out to be part of a set for a movie called Jurassic Hero and Bean is added to the cast and becomes the star.
