What’s a filmmaker to do if they need to make an 80s slasher film but the trend is getting long in the tooth? Add some inappropriate folklore!

A group of campers is stalked by a Viking berserker in the appropriately titled, BERSERKER (1987). 

And then a group of young people are mysteriously invited to their old summer camp built on land cursed by a medicine man in TWISTED NIGHTMARE (1988).
