This was the student film that George Lucas did way before he became successful in cinema.
4 years before he made the THX 1138 film. He created this short film which is very well written.
The whole short has to do with THX, an individual trap in a sick twisted world. Which he tries escape throughout the whole short.
It's very different from the full length film. But those who are curious to know what the earlier version is. This one's definitely an early version.
All great director start somewhere in their careers. And this is a fine example of a student film.
It's available on the THX Director's Cut DVD.
