THX 1138 is most interesting. Rather it's as a stunning montage of light, color and sound effects that create their own emotional impact ... Lucas's achievement in his first feature is all the more extraordinary when you realize that he is 25 years old, and that he shot most of the film in San Francisco, on a budget that probably would not cover the cost of half of one of the space ships in Stanley Kubrick's 2001."
