What's a film that you will never stop talking about, because its so great?

You know, the film that when people ask 'I need recommendations?'
you'll still say the film if it has little in common with what's being
asked, you'll bring it up ALL the time, etc. So really, what movies
are you obsessed with to the point that you fear you are annoying
people?

Don't expect me to stop talking about The Matrix, Kill Bill, Leon,
American History X and Moulin Rouge! any time soon!

BQ: Favourite WWII film?
Great choices, everyone.
