Tell me about an old movie you love - define "old" how you like, but nothing 21st century - and explain why more people ought to watch it. Looking for hidden gems over headliners, so try to pick movies you feel like the average person might not have heard of. Basically, Kirk Douglas died and I feel sad I haven't watched more than I have, and it makes me wanna watch and talk about movies. And while plot points are prolly essential, no spoilers :)
