It's sometime in the future in a state controlled society, where conformity and homogeneity are the rule. What is also the rule is that the populace follows the wants of the faceless state without question. How this is achieved is through a mandatory drug regimen, which also suppresses human desire, with sexual intercourse and human relationships banned. The law of the state is policed by a force of robocops. The physical environment is totally within a manufactured enclosure, what being outside of this unknown. THX 1138 is a loyal subject, he who goes about his business as a skilled factory working building robocops. And even when he begins to have strange feelings, he does what is obliged by going to the state run confessional, which further brainwashes through its reinforced mantra of happiness, loyalty and understanding. THX 1138 is given a glimpse into the other side through his computer matched and thus appointed female roommate, LUH 3417, and her surveillance colleague SEN 5241... Written by Huggo

"Drug Abstinence Felony"
10 April 2012 | by tim-764-291856See all my reviews

In George Lucas' 1971 view of 25th century "life", it's not the taking of drugs that lands you in trouble with the 'chrome robots' (police) but the NOT taking of them, for this is a chemically controlled population and environment. And, as ever, a couple of rebels try to break free from these chains....

Robert Duval (THX1138) goes through withdrawal symptoms as he stops the pill-popping, gets his libido back and makes love to his mate, LUH (Maggie McOmie). In a CCT governed environment these felonies don't go unnoticed and THX1138 is charged with sexual deviancy and drug abstinence. It soon comes clear that his sentence will be death and his body used for organ transplantation.

Naturally, Duval and other inmates of the 'detention unit' decide to escape, through the labyrinth of tunnels and with about the only action in the entire film, in futuristic cars, all the while, the soul-less robot policemen in pursuit use pleasant pre-recorded warnings.

I'd not seen or heard of THX1138 until looking up George Lucas on the IMDb. Then, I wondered if a snippet of memory from decades ago of a nude couple in a huge white void being approached by robots was one of the very same. And, yes, so it was, and is. I don't know when, or where I'd seen it before, but the pertinent thing was, that it had imprinted something indelible into my psyche.

Which is a mark of a good film. Not the chases at the end, which to many seem to be the only bits worthy of mention. To me, it is the minimalist, art-house sets that are both the most disturbing and memorable, of rows and rows of technicians and lab assistants. The story now, has been used a lot by now so that it's hardly original, but back 41 years ago (yes!, almost as old as I am) it must have painted a very chilling picture indeed.

It's also quite a dour, solemn picture; contrast that to say, 'Logan's Run', that at least some semblance of freedom on the outside that the couple had sampled and wanted to bring back to their City. I won't spoil those who've not seen THX how code no. 1138 fares and whether he finds freedom, or not.

Overall, a sobering, intelligent and superbly designed film rather than a great epic, far-reaching odyssey that Lucas was to move onto, of course. There are big hints at Lucas' genius at work here, this being his debut release, such as the robotic policemen and the ideas that he was to take into Star Wars.

One then, for the George Lucas fan club and for sci-fi enthusiasts. Mainstream audiences may well be a bit bored and baffled. The script is often confusing, with either nothing said and visuals only to tell us what's going on or, as with the rantings of Donald Pleasance in the Detention Unit, distracting and unnecessary to the story. These faults aside, this is a good sci-fi film, one to jostle the mind and a good grounding from which Lucas made such an epic career.
