The following is material I wrote for the Labyrinth wiki. You can access the article here, where it is fully referenced (and illustrated!)- http://labyrinth.wikia.com/wiki/Labyrinth_(film) I really hope you find it interesting. If you have anything you think should be added/needs correction, let me know! According to the film's conceptual designer Brian Froud, Labyrinth was first discussed between himself and director Jim Henson during a limousine ride on the way back from a special screening of their 1982 fantasy film The Dark Crystal. Both agreed to work on another project together, and Froud suggested that the film should feature goblins. On the same journey, Froud "pictured a baby surrounded by goblins" and this strong visual image - along with Froud's insight that goblins traditionally steal baby's - provided the basis for the film's plot. According to Henson, Froud made the suggestion that the film should feature a Labyrinth. Froud produced a range of concept paintings and sketches that informed the overall look and feel of the finished film. Several of these feature a young girl journeying through the Labyrinth with Hoggle and other assorted goblins, and this girl appears to be an early version of Sarah. Discussing the film’s origins, Henson explained that he and Froud “Wanted to do a lighter weight picture, with more of a sense of comedy sinceDark Crystalgot kind of heavy - heavier than we had intended. Now I wanted to do a film with the characters having more personality, and interacting more.” Labyrinthwas being seriously discussed as early as March 1983, when Henson held a meeting with Froud and children's author Dennis Lee.Lee was tasked with writing a 90-page novella that would become the basis for Terry Jones’ script of the film, turning it in at the end of 1983. One of several early ideas being discussed in the early stages of the film's development was that the lead would be a King whose baby had been stolen and placed under an enchantment. Alan Lee - Froud’s collaborator on the illustrated bookFaeries– observed that this plot seemed similar to that of Ridley Scott’sLegend, and Henson and his creative team went back to the drawing board. Ultimately the decision was taken for the film’s lead character to be a young girl, as according to Henson “That hadn't been done very much.” The protagonist went through several different incarnations before it was decided that she should be a teenage girl from contemporary America. Henson noted that he wished to “make the idea of taking responsibility for one's life - which is one of the neat realizations a teenager experiences - a central thought of the film." With this in mind, 14 year old actress Jennifer Connelly was cast in the role. According to Henson, Connelly "could act that kind of dawn-twilight time between childhood and womanhood." The character of Jareth also underwent some significant developments during the early stages of pre-production. According to Henson he was originally meant to be another creature in the same vein as his subjects. Henson eventually decided he wanted a big, charismatic star to the play the Goblin King, and developed the role with David Bowie in mind. Henson met David Bowie in the summer of 1983 to seek his involvement, as Bowie was in the U.S for his Serious Moonlight tour at the time. Henson continued to pursue Bowie for the role of Jareth, and sent him each revised draft of the script of the film. Bowie only formally agreed to take part a few weeks prior to the start of filming. While Terry Jones is credited with writing the screenplay the shooting script was actually a collaborative effort that featured contributions from Henson, George Lucas, Laura Phillips, Dennis Lee and Elaine May. Jones himself has said that the finished film is very different from his version of the script. According to Jones, “I didn’t feel that it was very much mine. I always felt it fell between two stories, Jim wanted it to be one thing and I wanted it to be about something else.” According to Jones, his version of the script was “about the world, and about people who are more interested in manipulating the world than actually baring themselves at all.” Jones script had Sarah realize there is no true solution to the Labyrinth, and featured a Jareth who used the Labyrinth to “keep people from getting to his heart.” Jones has said that Bowie’s involvement in the project had a significant impact on the direction taken with the film. Jones had originally intended for the audience not to see the centre of the Labyrinth prior to Sarah’s reaching it, as he felt that doing so robbed the film of a significant ‘hook.’ With the thought of Bowie starring in the film in mind, Henson decided he wanted Jareth to sing and appear throughout the film, something Jones considered to be a ‘wrong’ decision. An early version of the script attributed to Jones and Phillips varies in several notable ways from the shooting script. The early script has Jareth enter Sarah's house in the guise of Robin Zakar, the author of a play she is due to perform in. Sarah does not wish for her brother to be taken, and Jareth does not set an ultimatum until Sarah has already made some head-way through the Labyrinth. The early script ends with Jareth transforming into a powerless, snivelling Goblin, an outcome that was ultimately abandoned in favour of that found in the finished film. After much tweaking and re-writing, the script was ready for filming. The Jim Henson Creature Shop in London had been producing puppets and costumes for the film since 1984, and filming finally started in April 1985 at Elstree Studios.
