I'll be watching The Killing in theaters this week.
That's my fav Jack Lemon comedy... I'd also want to say The Apartment but that was made in 1960 so I guess that doesn't count.Marilyn Monroe's Some Like It Hot is a really fun film and might have one of the greatest ending lines ever.
Well you can't go wrong with that.I have many. I won't make a giant list. Suffice it to say, there are some real gems out there in classic cinema. If I absolutely had to pick, I would probably say Paths of Glory (1957).
Wings should get more love, such an amazing movie with some really breathtaking cinematography that still holds up to this day.
It's got everything, awesome aerial dogfighting, romance, drama, also one of the first same-sex kisses on screen,
It's been mentioned several times here already, but 12 Angry Men is just so dang good. I first saw it in the late 90s when I was in middle school, and even back then I found it gripping.
Ace In The Hole
M
Woman in the Window
Rififi
Dial M For Murder
Rififi and M are a notch above the others.
Edit; The Killing, which is probably my favourite of them all .
