Fright (1971)
I was watching an interview with the late George Cole where he mentioned this film. He said that when he and Dennis Waterman were first cast in Minder, neither of them realised they had both appeared in the same film before! Anyway, I was intrigued enough to check the film out, especially when I saw the lovely Susan George was the lead.
I found the whole film on youtube.
Not a bad film overall. I especially liked the first half and the way the suspense built up. It reminded me of the early seventies Hammer films, but it is also very original and must have been an influence on later films like Halloween and When a Stranger Calls.
Only Fools & Horses fans will also recognise a young Roger Lloyd Pack playing a policeman!
