One of the best British cult films ever, has to be the brilliantly weird biker/horror flick PSYCHOMANIA with Beryl Reid as a Satanic-worshipping granny trying to stop her biker-mad son from being a bad boy.
The bike chase around the town, where the bike gang terrorise the locals, is hilarious, as is the scene where the head biker (is his name Tom, as I can't recall?) is reborn, and leaps out of the grave, on his motorbike!
Fantastic film, and highly underrated! A classic of British cinema!
