I first saw this in the early 90s on a vhs n had a solid wtf reaction regarding the notorious rape scene of the buxom babe.
Revisited it recently.
The plot is basically a rip off of Alien but the film has some well known horror veterans, Sid Haig n Robert Englund. It also has erotic film director Zalman King.
Inspite of the film being a Roger Corman production, it has some well done effects due to the involvement of a very early James Cameron.
Cameron must be laughing at the thrusting movement of the giant worm.
