This classic horror-comedy is perfect watching for those who prefer a bit more offbeat Christmas movies.
In this film a father (Hoyt Axton) buys a cute little creature as a Christmas gift for his son Billy (Zach Galligan). However, he is given three rules, keep him out of the light, keep him away from water and never feed him after midnight. Naturally it isn't long until these rules are broken, and a swarm of monsters are unleashed upon the city of Kingston Falls (which bares more than a little resemblance to the town of Bedford Falls from It's a Wonderful Life (1947)).
This is everything one could want from a horror comedy. There are some scenes here that are legitimately creepy. However even these scenes are balanced with a sense of dark humor. Some of this humor almost resembles a Looney Tunes short in its level of cartoon-y absurdity. The gremlins singing Christmas carols, enjoying watching Snow White and the Seven Dwarfs (1937) in a movie theater, acting like rowdy bar patrons and breaking into a candy store simply makes these characters a lot of fun to watch despite their violence and scary appearance. It is this mixture of frights and laughs that make this film so much fun. However, this is not the only joy of this movie. Gizmo (the original gremlin) is incredibly adorable in a way that helps bring a certain charm and likability to a film that could have otherwise been too dark and mean spirited. The same can be said for the young romance between Zach Galligan and Phoebe Cates. Zach Galligan was given the role because he showed great chemistry with Phoebe Cates during the auditions. That great chemistry can be felt here. Though this is not really a romantic film, there is a sweetness to the young romance here that feels completely natural. This helps make us like these characters almost instantly, which again helps this movie from becoming too mean spirited. The movie also makes great use of its Christmas time setting. The juxtaposition of the violence and the Christmas imagery adds a lot to this movie's dark humor. As does the various sendups of Christmas movies throughout. The Christmas setting also gives a somewhat warm and charming feeling to the early scenes, which makes the later release of the Gremlins upon the city both funnier and more frightening.
Despite the mixture of horror and comedy being one of this film's main features, the movie wasn't originally conceived this way. Hearing the scampering of mice as he was trying to sleep, gave screenwriter Chris Columbus the idea for this film. He wrote a script that was straight horror. In this script the gremlins were not humorous or fun in any way and their violence was even more intense. This script found its way to Steven Spielberg, who thought the idea was very original. He bought the script to produce it at his new production company, Amblin Entertainment (this was the first movie to carry the now famous Amblin logo). However, Spielberg also knew that much had to be done before this script was ready to become a movie. He suggested that the horror and violence be toned down a bit and that Gizmo would stay a cute and lovable creature instead of being transformed into a monster like the rest of gremlins. Tim Burton was briefly thought of to direct this movie. Burton at this time had not directed a single feature length movie but a short film he directed called Frankenweenie (1984) would bring him to be considered. However the directing job instead went to Joe Dante who at this time had directed such horror movies as Piranha (1978) and The Howling (1981). Dante would bring in much of the film's sense of humor. Dante also came up with the idea to make the early scenes much warmer, like a traditional Christmas movie. He felt that with this, "even the smallest amount of violence became more intense."
This movie along with Indiana Jones and the Temple of Doom (1984) (which was released only two weeks earlier), would help lead to the PG-13 rating. Both of these films angered parents who thought they were bringing their kids to something more age appropriate. Later that same year Red Dawn (1984) would become the first movie to receive a PG-13 rating.
With its Christmas time setting it may seem strange that this movie was released during the summer. This came because Warner Brothers (who was distributing the film) realized that they did not have a big summer movie to release opposite of the likes of Indiana Jones and the Temple of Doom and Ghostbusters (1984). Because of this the movie's release was moved up from its original Christmas time release to a summer release. This however did not hurt the film's success at the box-office as this would become the 4th highest grossing film of 1984.
