Psycho IV Bloopers: Norman's age when started killing.
When the first Psycho was made by Hitchcock in 1960, Norman had to be about 25 or 30. Say Norman was 25 in 1960 and was therefore born in 1935. Hence, when his father died from the bee stings, Norman was six - the year was 1941???? Is the depicted well in the funeral scene flashback? Norman was 15 when he killed the girl who wanted to seduce him, the year was 1950, the clothes everyone wore looked seventies and eighties. THIS FILM HAS NO TIME OR ERA PLANNING TO IT WHATSOEVER!
Next, Norman (Perkins) on the telephone to the radio show talking with Olivia Hussey, he says that he killed his mother and the boyfriend "slowly" after he had killed the girl who tried to seduce him (this was Norman's debut or premiere into the world of killing) and after the older woman he was kissing in the car (scene where he strangled her and buried the car in the swomp for the first time).
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAH. HUGE BLOOPER! When the girl seducing Norman entered the house, he went into his mother's room. His mother was dead and he imagined her telling him to stab the girl.
So you see, members of the jury, how could Norman have killed the girl who seduced him as his first murder, when his dead mother told him to do so - he killed the mother first. Do the writers not plan these things out professionaly.
