Me, my current and for a long time favourite movie is French Kiss with Meg Ryan. It is over 15 years old. Dh bought it on VHS for me and when the tape wore out he special ordered it on DVD for me. It is a simple romance.
DH's favourite movie is Zoolander. He can quote entire sections of the dialogue. He uses it when interviewing new hires. So far every geek he has hired knows the movie and has a favourite scene.
Recently I really enjoyed the Marigold Hotel one, cannot remember the whole name.
