the haunted house of horror (1969)

aka Horror House. The Dark.
"No-one's going to go running off or running to the police. We have got to figure this out for ourselves!"
Some hip young Londoners, (and Frankie Avalon), are typically bored and looking for some kicks. So they head to the local haunted house on a ghosthunt. Once there one of the gang is brutally hacked to death. Chris (Frankie Avalon) comes to the conclusion that it must be one of them. So with some twisted logic, they decide to hide the body and try and puzzle it out. Then the police get involved and start asking questions. The gang then decide that the only way to solve it is to re-enact the night, and thus return to the house one last time!
A rather uneven film, that seems to spend an eternity setting up the characters and premise, and what a dodgy premise! If I thought one of my friends was an insane murderer, I think I'd be down that police station in two seconds flat, but then I'm not a typical 60's hipster. One to watch if you want some grizzly murders and some hip Carnaby St scenes.
