Title:
Steven_Spielberg

Context:
His next directorial feature was the Raiders prequel Indiana Jones and the Temple of Doom. Teaming up once again with Lucas and Ford, the film was plagued with uncertainty for the material and script. This film and the Spielberg-produced Gremlins led to the creation of the PG-13 rating due to the high level of violence in films targeted at younger audiences. In spite of this, Temple of Doom is rated PG by the MPAA, even though it is the darkest and, possibly, most violent Indy film. Nonetheless, the film was still a huge blockbuster hit in 1984. It was on this project that Spielberg also met his future wife, actress Kate Capshaw.

Question:
Why did Gremlins need 'PG-13'?
