In Melbourne they used to have something called to Moonlight Cinema (I think). On a warm summers night, they'd set up a projection screen in the Royal Botanic Gardens. It was a beautiful way to see a movie! Except that night they played Clockwork Orange. I expect a lot of people turned up for the ambience rather than the actual movie. Not quite the ambience they were expecting, it was the weirdest vibe I've ever experienced at a movie. I don't there's any safe age for that movie.
