Teenage Mutant Ninja Turtles II: The Secret of The Ooze

Teenage Mutant Ninja Turtles II: The Secret of the Ooze is a 1991 American live-action film. It is the sequel to the 1990 film, Teenage Mutant Ninja Turtles. The Secret of the Ooze was then followed by a third film in 1993, and a fourth film (TMNT) in 2007. The film is commonly abbreviated as TMNT II. The movie is distributed by New Line Cinema. Outside the United States, it is internationally distributed by 20th Century Fox.

The film follows the adventures of the four Turtles: Leonardo, Donatello, Michaelangelo, Raphael, and their Master Splinter. Roughly resuming from the events of the last film, the villain, Shredder, returns to take back command of the Foot Clan, and work towards getting revenge on the Turtles. When he learns the secret behind the Turtles' mutation, he becomes more dangerous than ever. The film sheds some light on the origins of Splinter and the Turtles, as well as introduces two new villains: Tokka and Rahzar.

Unlike the first film, this one rarely showed the use of the Turtles' weapons. They instead fight bare-fisted for much of the film as part of an attempt to tone down the violence of the previous movie. The film was released on March 22, 1991, and received mixed reviews from critics. It departed from much of the darker tone of the 1990 film, and was more light-hearted. The film was successful, and it became the 13th highest grossing film domestically in the year of its release.
