The Incredible Mr. Limpet was a 1964 film starring Don Knotts as a man who magically turns into a fish and helps the Allies win World War II. It was a mix of live action and animation, and Mr. Limpet was drawn as a fish who had Knotts' most recognizable features. The movie was not a big hit, and today has a 40% rating on Rotten Tomatoes. I loved it, only because I was five years old. So you might be surprised to learn that Hollywood spent years trying to produce a remake starring Jim Carrey.
The problem was that Carrey would be an animated fish for most of the film, and in the late '90s, he was a superstar and just too expensive to star in a movie in which his face wouldn't be shown. They tried to work about that by animating a fish with a photorealistic rendering of Carrey's face using motion capture technology. The results were terrifying, much worse than the drawing shown here. The movie was in development for around 18 years, but the core problem was never really solved, so the project ran out of steam and was abandoned.
