Growing up in a sports-loving family, there was more likely to be football on the TV rather than movies. So there are a lot of classic films I have never seen. Some of my friends go into a state of shock/start squealing when I tell them what they are...
Some of the movies include:
Back to the Future
And there are probably more, but those are the ones that spring to mind. Shocking, eh?!
I try to watch Back to the Future - but it's always part 2 or part 3 on TV. I think i started to watch the first one ages ago, but got put off by the strange make-up (where one of the young actors had obviously been made up to look like an old man).
