WHEN HARRY MET SALLY…, which celebrates its 25-year anniversary this month, tells the oscillating love story of the two title characters. The film also includes several scenes of other couples who — straight to the camera — passionately and matter-of-factly explain how they wound up with one another. While those touching and humorous stories are portrayed by actors, the accounts themselves are true.

In this exclusive clip, director Rob Reiner touches upon the memorable moment that inspired him to include those real stories in the film.
