As revealed in "The Art of Star Wars: Episode I – The Phantom Menace", director George Lucas conceived the character of Qui-Gon Jinn during pre-production of the film. This is shown by concept art where Obi-Wan Kenobi is shown alone in the Trade Federation flagship and while meeting Jar Jar Binks. Even when Qui-Gon was conceived, Lucas toyed with making him the younger Jedi, as shown in concept art depicting Obi-Wan as an older man. Lucas originally envisioned an American actor for the role of Qui-Gon, but ultimately cast Northern Irish actor Liam Neeson because he considered Neeson to have great skills and presence, describing him as a "master actor, who the other actors will look up to, who has got the qualities of strength that the character demands." Initially, Lucas had planned for Qui-Gon to have long white hair, but that idea was scrapped and Qui-Gon is depicted as having long brown hair in the film.
