Koyaanisqatsi is a twenty year old movie that is being released on DVD on September 17th. The title means "life out of balance" in Hopi.
It has no explicit plot (although there is an implicit message in the film), and no dialogue. It is a stunning montage of natural and man made scenes. The music that accompanies the film is by Philip Glass.
If the techs have done well with this flick, it ought to be spectacular on DVD!
