Oh, you are right coyote522, we left out the Marx Brothers till now (!)
Bicycle thieves should be in the top ten movies of all time.
I like Soliti Ignoti, but don't stay up to watch it every time - in fact the same about Bicycle thieves - it is a great, great film, but sometimes it is too sad, really heartbreaking and if I am not in the mood for that I can't bear it and don't watch it just cause it's on. Il Postino is in the same category - great film but too sad if I am not up for that.
I don't know Big Deal on Madonna Street. I will look for it. I don't know the others you mention either - so you have given me some homework to do. Thanks !
