Dead Ringers (1988) a more "mainstream" (but still awesome) side of 80s Cronenberg with a brilliant performance by Jeremy Irons playing identical twins; deals with issues of psychological autonomy and substance abuse
general impression: fuck, this is great, what the hell was i thinking, why didn't i watch this years ago (like everyone else on this board probably did)
Húsið: Trúnaðarmál (1983) a supernatural mystery / family drama hybrid from Iceland
influences from The Changeling, Rosemary's Baby and nordic drama (Ibsen?) melted into something quite unique
at times a bit too slow, at times genuinely creepy and thrilling without relying on any cinematic bells & whistles, at times deeply touching
+ a pretty efficient punch-in-the-gut ending
all in all, one of the rare examples of a haunted house movie that doesn't suck balls
