10 Movies That Show You Shouldn’t Trust Strangers

10. Psycho (1960)

The original dangerous stranger, Norman Bates appears as a charming, innocent, friendly face when he checks Marion Crane in on her rainy night on the run. His boyish manner makes him seem so unthreatening, so it is understandable that she would never have suspected how the events of the night would unfold. When she hears him arguing with his 'mother', this further cements this persona, as he seems to be so child-like that he still lives with her and needs her to look after him.

He kindly brings her some food and drink and tells her his story about the issues his mother has, making her sympathise with him as it draws parallels to her own life. Although her murder in the shower is so well known now, it was truly shocking to audiences at the time, which was a testament to how well Anthony Perkins portrayed the character.

He continued to fool the audience right until the horrible reveal at the end, showing that it wasn't just Marion who would have been taken in by him as a trustworthy person. He also stopped a fair few people using shower curtains after watching the film!
