Found another one this weekend. Another sci-fi movie where all the space footage is lifted from "Battle Beyond The Stars"
This one is...
"Last Exit to Earth" (http://us.imdb.com/Title?0116829)
..another Corman production, naturally
Found another one
"Cyberzone" (or "Droid Gunner"...neither name fits the movie too well)
As one IMDB reviewer says "Blade Runner on a budget"
I picked this one up because it has Marc Singer, whom I happen to like
There is one scene early on where some Space Combat occurs and, naturally, the footage is lifted from "Battle Beyond The Stars"
And of course, the executive producer is Roger Corman
