What are some movies that were way better than you expected them to be? Leo is about a class pet iguana and turtle that slowly reveals to the class he can talk and helps them with their home life problems. It was written by Adam Sandler and he plays Leo the iguana. I thought this was going to be kids slop but it was a lot funnier and heartfelt than it needed to be. Certainly better than anything Dislop has made in years
