Here's one from my childhood. This is the trailer for Alvin Rakoff's 1980 flick Death Ship.
I believe I originally caught this on late night television. If I was making a master list of scenes that haunted my childhood, that blood shower scene would probably make the top ten. Now that I think about it, a good number of scenes at the top of the pile involve water. But I've crossed that sea before.
It's been at least thirty years since I've seen Death Ship last, so I have no idea if it still holds up, but I wager it is still better than Dark Castle's 2002 attempt to rip it off.
