One of the most beloved romantic comedies of all time is now 30 years old. "When Harry Met Sally" is a terrific reminder that the best rom-coms are truly timeless. Celebrate this anniversary with some fun trivia about the making of this modern love story.

1. Both director Rob Reiner and writer Nora Ephron drew from their own personal lives while making the film. Ephron based Sally on herself and several friends, while Reiner's struggle with his divorce influenced the portrayal of Harry.
