Sally Field once said on the A&E television show James Garner: Hollywood Maverick (2000) that her kissing scene with Garner in this picture was the best on-screen kiss she had ever had.
Columbia Pictures really wanted Marlon Brando for his "box office allure", even though he hadn't been in a film since 1980. James Garner had played the lead male role in Victor/Victoria (1982). Martin Ritt and Sally Field insisted on Garner being in this film, resulting in his only Academy Award nomination.
Reportedly, Columbia Pictures studio did not want to make the movie at all, because it had no "sex or violence" in it.
The Lunch Counter is in Florence, Arizona. It is in the General Store about one block south of the movie location.
