Oh, I just remembered something
The company of wolves:
This picture was printed on the back of the VHS box I saw while casually browsing through movies to rent at the local store.
I was 8/9 and this gave me nightmares for months.
(of course though, i still had to rent the video and watch the movie, which iirc consisted of of 7 episodes, each a different take on the werewolf theme and varied greatly in mood and cinematography: dark, humourous, scary, sexy..)
Full transformation scene here, still have a hard time handling it for some reason.
Enjoy this guy peeling his skin off !
Oh and of course this motherfucker right here:
used to love Creepshow as a kid,
Wasn't too scared with the rest of the movie, but this guy just standing (floating, likely) just looking at you through the window...my curtains remained closed for a while.
