Burt Reynolds once said of his co-star Goldie Hawn in this movie: "Goldie Hawn and I had been talking for five years about doing a movie together. She's someone who makes me laugh. Really laugh. I knew her when she was a dumb blonde and even then she was one of the smartest people I knew" and "We'd meet for dinner and compare notes on the scripts we'd read and liked, but we always ran up against the same problem. The male role always dominated the female character or vice versa. They didn't seem to be writing the kind of give-and-take comedies that Tracy and Hepburn [Spencer Tracy and Katharine Hepburn] or Cary Grant and Jean Arthur used to do."
The film's writers Barry Levinson and Valerie Curtin based the script on their very own marriage. Show-business trade paper 'Variety' stated in their review that the married couple screenwriters "are said to have based at least part of this work on their own relationship."
Goldie Hawn was Golden Globe nominated for Best Actress in a Motion Picture - Comedy or Musical for her performance in this picture but lost out to Julie Andrews for Blake Edwards' Vítor ou Vitória? (1982).
The house in Buffalo seen in the picture, located at Summit Avenue in that city, was chosen from hundreds of homes that responded to an advertisement placed in a local newspaper by the production's New York location manager Eric Young.
This movie's screen-writers Barry Levinson and Valerie Curtin separated around the time that this picture was first released. This movie that they wrote was semi-autobiographical.
