A couple of great Audrey Hepburn movies during the 60s were Wait Until Dark and Charade.
Some of my other favorites from the 60s and 70s include:
-Guess Who's Coming To Dinner (Spencer Tracy's last movie) (1967)
-Lilies of the Field (1963)
-To Sir, With Love (1967)
-The Day of the Jackal (1973)
-The Great Escape (1963)
-Foul Play (1978) Great comedy with Goldie Hawn and Chevy Chase's first movie
-Seems Like Old Times (1980) I know it's the 80s, but this is the second movie that Goldie Hawn and Chevy Chase, so if you enjoy one of them, you'll enjoy both of them
-What's Up, Doc? (1972) I know it's Barbra Streisand, but there's only one song she sings, but it's a great comedy with Ryan O'Neal and Madeline Kahn's first movie
-Young Frankenstein (1974)
-Oh, God! (1977) John Denver stars in this movie
-Close Encounters of the Third Kind (1977)
-Same Time, Next Year (1978)
Okay and some of my favorite classic movies are On Golden Pond, Yentl, Peyton Place, Tootsie, swedish movie Kapo, and Some Like It Hot.
