Gremlins is an American comedy horror film directed by Joe Dante and released in 1984 by Warner Bros. It is about a young man who receives a strange creature (called a mogwai) named Gizmo as a pet, which then spawns other creatures who transform into small, destructive, evil monsters. This story was continued with a sequel, Gremlins 2: The New Batch, released in 1990. Unlike the lighter sequel, the original Gremlins opts for more black comedy, which is balanced against a Christmas-time setting. Both films were the center of large merchandising campaigns.

Steven Spielberg was the film's executive producer, with the screenplay written by Chris Columbus. The film stars Zach Galligan and Phoebe Cates, with Howie Mandel providing the voice of Gizmo. The actors had to work alongside numerous puppets, as puppetry was the main form of special effects used to portray Gizmo and the gremlins.

Gremlins was a commercial success and received positive feedback from critics. However, the film has also been heavily criticized for some of its more violent sequences. Critics alleged these scenes made the film inappropriate for younger audiences who could be admitted into theatres under its PG rating. In response to this and to similar complaints about other films, the Motion Picture Association of America (MPAA) reformed its rating system within two months of its release.
