M. Hulot's Holiday. I was taken to it by an aunt as a 'treat'. Mime leaves me cold, no not cold, has me running screaming for the hills.
I wouldn't describe 'Brief Encounter' as the worst film ever, but certainly grossly overrated. I always reckon that if the couple had gone off together it wouldn't have lasted 6 months. Just until they had each shown each other their ordinary everyday personalities and they had discovered they really had nothing in common.
Then there was an unnamed B film, forget what A film it accompanied. It was silent and contained a miserable looking knight with a bored horse, wandering round a small castle on a blasted moor and looking 'significant'- and that was all. Finally he rode away from the castle and the film ended. There were 5 of us in our party DH and I, his mother and two children around secondary school age. None of us understood it. But we talked about it for ages after, trying to work out what the point was.
