Oh god, just about ANYTHING on basic cable TCM ...
Some of my favorite oldie movies -- I actually think a few are from the 60s:
Some Like It Hot (actually just about anything with Jack Lemmon, most of marilyn monroe's stuff was pretty good too)
Bell Book and Candle (jack lemmon again)
Arsenic and Old Lace (actually, just about anything with carey grant for that matter)
Will Success Spoil Rock Hunter
Anything with Spencer Tracy & Katherine Hepburn (Guess Who's coming to Dinner?, Pat & Mike, Woman of the Year)
By Yul Brynner: Tarus Bulba/the Magnificent Seven/The King and I
By Humphrey Bogart: African Queen/Maltese Falcon/We're No Angels/The Caine Mutiny
Rex Harrison: The Ghost and Mrs. Muir/Dr. Doolittle/My Fair Lady/Anna and the Kind of Siam (which is the "nonmusical" version of the king and I, slightly different take on the same story).
That list should get you started.
