Ideas for the film began when Reiner and Penny Marshall divorced. An interview Ephron conducted with Reiner provided the basis for Harry. Sally was based on Ephron and some of her friends. Crystal came on board and made his own contributions to the screenplay. Ephron supplied the structure of the film with much of the dialogue based on the real-life friendship between Reiner and Crystal. The soundtrack consists of standards from Harry Connick Jr., with a big band and orchestra arranged by Marc Shaiman. For his work on the soundtrack, Connick won his first Grammy Award for Best Jazz Male Vocal Performance.
