The 1960 one - a comedy, but with actual sadness mixed in. I must admit, I was prompted to watch it because I saw Shirley Maclaine's character on a list of manic pixie dream girls and was intrigued; she's fetching, but not an MPDG. Jack Lemmon's likeable too, and seeing him as a young man is interesting...I just read that his performance in this film was one of the iconic American roles upon which Kevin Stacey based his character in American Beauty, and I can see it.
