I am a big fan of Alfred Hitchock, actually was given a collection of his first movies he made after he came to the US with Peter Lorie, some are unbeviably funny.
Now what I believe is his masterpiece is ' M ' filmed in Germany with English sub titals before he came here about a Child Molester. The station that aired this way old time film went blank just in the last few minutes of the film due to power outage, I have looked everywhere to find that film, so far no luck-----.
Then my favorite Alfred Hitchock Hour story aired in 1963 was the " The Hangover" with Jane Mansfield and Tony Randel-------- Lots of really wierd storys in the late 50-1960 the most disturbing are about evil children, the kind that are so realistic one wonders about their own kids.
Mordern day Bullys that look so sweet, so caring and lovable as they torment those around them. Tip offs are one never knows if the child is responcible for acts of arson or the death of neighborhood cats. Lots of clues, close ups to the childs face as they lie or smerk when their lie is believed. A Master to detail that we do not get in todays movies.
The really scarey thing is there is nothing SCIFI, no extra powers, to his actors, just a feeling that ---This can happen to you.
