Gremlins: Unleashed!

Struggling inventor Randall Peltzer visits a Chinatown antique store to find a Christmas present for his son, Billy. In it, Randall uncovers a small and furry creature called a mogwai (Cantonese: 魔怪, 'devil'). The owner, Sam Wing, refuses to sell it to him, but his grandson secretly does, warning Randall to remember three important rules concerning its care – keep the mogwai away from light, especially sunlight, which will kill it; do not let it come in contact with water; and above all, never let it eat after midnight.

In Randall's hometown of Kingston Falls, Billy works at its local bank, but fears that his dog Barney will be put down by widowed miser Ruby Deagle. His father returns and offers him the mogwai, now named "Gizmo", as a pet and informs him of the rules. Gizmo is friendly and docile, but when Billy's friend, Pete Fountaine, accidentally spills water on him, five more mogwai spawn from him – a more mischievous sort led by the aggressive Stripe, named after the mohawk-like tuft of white fur on his head. Billy shows one of the mogwai to his former elementary school science teacher, Roy Hanson, spawning another mogwai, whom the latter experiments on.

Gremlins was produced at a time when combining horror and comedy was becoming increasingly popular. According to Professor Noël Carroll, Ghostbusters, released the same weekend as Gremlins, and the comic strip The Far Side also followed this trend. Carroll argued that there was now a new genre emphasizing sudden shifts between humorous and horrific scenes, drawing laughs with plot elements that have been traditionally used to scare.

The notion of gremlins was first conceived during the 1920s when mechanical failures in RAF aircraft were jokingly blamed on the small monsters. The term "gremlins" also entered popular culture as children's author and RAF pilot Roald Dahl published a book called The Gremlins in 1943, based on the mischievous creatures. Walt Disney considered making a film of it. A Bugs Bunny cartoon of the era, Falling Hare, shows Bugs battling a gremlin on an airplane.

Financially, Gremlins was a success. Produced on an $11 million budget, it was more expensive than Spielberg had originally intended but still relatively cheap for its time. The trailer introduced the film to audiences by briefly explaining that Billy receives a strange creature as a Christmas present, by going over the three rules, and then coming out with the fact that the creatures transform into terrible monsters. This trailer showed little of either the mogwai or the gremlins.

The film not only spawned the sequel (another sequel is scheduled for an October 2028 release) and an advertisement for British Telecom, but is believed to have been the inspiration for several unrelated films about small monsters. These include Ghoulies, Troll, Hobgoblins and Munchies.

In music, the Scottish post-rock band Mogwai is named after the film's creatures: as for the reason why the band chose this as their name, their guitarist, Stuart Braithwaite, has stated that "it has no significant meaning and we always intended on getting a better one, but like a lot of other things we never got round to it". Welsh singer and songwriter Rod Thomas performs under the name Bright Light Bright Light, which is a direct quote from the film.
