10 Things You Didn't Know About 'When Harry Met Sally...'
The personalities of the Harry and Sally characters were based, in part, on director Rob Reiner and screenwriter Nora Ephron.
In the introduction to the book adaptation of the 'When Harry Met Sally...' screenplay, Ephron (who passed away in 2012) explained that she based Harry’s proclivity toward pessimism on Reiner’s own depressive streak. As for the always-happy, high-maintenance Sally, Ephron needed to look no further than the nearest mirror. “I began with a Harry, based on Rob,” she writes. “And because Harry was bleak and depressed, it followed absolutely that Sally would be cheerful and chirpy and relentlessly, pointlessly, unrealistically, idiotically optimistic. Which is, it turns out, very much like me.”
