Recommended old movies

The other day I was thinking about how I don't really watch old movies anymore ("old" meaning pre-1970). I used to try to watch more, mostly as a matter of education. I'd rent Hitchcock classics and old musicals or watch TCM. Some were admittedly a little too dated for me, the acting too unnatural, the material a little too censored. But of the relatively few old movies I've watched, those that I've liked, I've liked a lot. Here are my personal favorites. Rent these if you haven't seen them, I can almost guarantee you will like them.

• Casablanca
• On the Waterfront
• Rebecca
• Vertigo
• The Best Years of Our Lives
• Rebel Without a Cause
• It’s a Wonderful Life
• Splendor in the Grass
• Singin’ in the Rain
