Teenage Mutant Ninja Turtles: The Movie is the live-action, feature film adaptation of the cult comic book and the popular animated television show. After prolonged exposure to radiation, four teenage turtles--Michelangelo, Raphael, Leonardo, and Donatello--have mutated into ninjas and have begun living in the sewers of a large city. Under the guidance of a ninja master Splinter the Rat and television reporter April, the Turtles embark on a mission to run crime out of the city and battle the warlord Shredder. The Turtles have been designed by Jim Henson Productions and effortlessly fit into the live-action surroundings.
