HUMANOIDS FROM THE DEEP (1980)

 This movie is great because what you get is basically an old-fashioned 50's style monster movie updated to the 80's with nudity and rape-happy mutant fish-men. According to this flick bad salmon causes fish to turn into horny humanoids and it all starts off with a bang as a kid gets killed and a boat explodes.  From there a dog gets throttled to death and it just gets nastier as we go on.  One of the weirdest things in this whole movie is probably the part where a ventriloquist gets killed and the eyes of his dummy keep moving back and forth like he was some kinda haunted evil dummy.  Unfortunately he never returns to battle the fish-people in a big devil-dummy Vs. killer walking-fish showdown.
 I've seen a lot of comparisons between this and THE CREATURE FROM THE BLACK LAGOON and I guess I can see that but this movie will never be thought of as the classic CREATURE is and it's also like 10 times as nasty as that 50's movie ever was.  This was made for Roger Corman's New World Pictures company and there are rumors that Corman had  additional scenes of gore and rape filmed when he wasn't happy with the finished product from female director Barbara Peters.  It certainly made the movie a lot less dull to me.(IMDB lists two directors because of this)
 A remake was done by cable channel Showtime in 1996 using some footage from the original but cutting out most of the sex and violence.  I guess this was because movies weren't allowed to be very exciting in the 90's.  Great job Showtime, now I'll never watch that.
