Because First Look is lame and they since they're owned by Nu Image who made this as a teaser they didn't want to spend money for another one, and they sent it to worldwide distributors who used it as well (UK, Spain, Brazil, Greece, Scandinavia etc etc)
Ended up double-dipping and picked up the Australian R4 DVD today on the cheap. Unfortunately "All Interactive" have decided to crop the film to full-frame 16:9 instead of 2.35:1! Very annoying.
I double-dipped on Direct Contact and it's the same, but it was filmed that way so that's okay!
