A rip-off of ALIEN (1979), this Roger Corman production has plenty of gore and a mindless storyline. A group of astronauts are sent to rescue a stranded spaceship. One is raped by a giant worm, another blows up, and a third cuts off his own arm. The special effects are excellent. Second unit director Jim Cameron went on to write and direct THE TERMINATOR (1984); ALIENS (1986); and THE ABYSS (1990).
