Retired to Spain, criminal ‘Gal’ (Ray Winston) receives an unexpected visit from Don (Ben Kingsly), a psychotic gangster determined to pull Gal out of retirement to do one last job.

Watch the classic airport scene.

There’s nothing better for a man to do than to take his best friend and head out into the American wilderness. It’s only great if you are NOT followed by two inbred hillbillies who ambush you, then rape your friend and force you to watch. So next the time you go camping make sure you go in numbers and stay the hell away from hillbillies. Here’s the scene when they first meet the hillbillies.

Ed Gein, a real murderer, inspired the movie. He was reknowned for cutting out a woman’s face and wearing it. Not because he had a deformed face (like in the movie) but because of his desire to be a woman. He was suspected of several murders, one of which where he gutted a woman like he would have gutted a deer and removed her head as a trophy. Here’s the trailer for the original film.

A couple head out to the open waters to help them get over their dead son while another ship not too far away is sinking.

Of course the guy they save is a homicidal killer! Never pick up strangers in open waters. Here’s the trailer.

Two girls and a guy take a road trip to the Australian outback. Their car breaks down in the desert where an old and seemingly harmless man decides to help them free of charge.

Living in a haunted hotel can really play tricks on your mind. Especially if people were murdered there – like the creepy twin girls who were killed by their father, the butler, before he also killed their mother and took his own life. After that incident the hotel was never the same. The family haunts the hotel together with a guy in the bear suit with the buttocks removed. Check out this scene.

Imagine yourself deserted after a car crash and the only person around to save you was your number one fan who’s stalking you. Now imagine a crazy person like Annie Wilkes who saves you from harm’s way and takes you into her home. She heals and nurtures you, then tells you that you can never leave. And on top of that she knocks of your feet with a sledgehammer! Here’s a scene.
