In 2000, a Danish animated film was produced called Help! I’m a Fish, the story of three kids who are forced to swim the ocean after taking a potion which turns them into fish. Help! I’m a Fish never got a major release in North America, but it was dubbed into English and was released theatrically in the United Kingdom. When you watch the trailer, you’ll probably instantly recognize Alan Rickman as the voice of the villain. But believe it or not, you’ll also hear the voice of a then-unknown Aaron Paul as Chuck, the overweight nerdy kid who becomes a fish.
