The cabin in Ontario, Big Bear Lake is the same filming location as Dr. Falken's house in WarGames (1983).
The restaurant that Bill and Lucia meet Dedee and Matt in was Chasen's in West Hollywood, which was once frequented by various big Hollywood stars and had booths named after such regular customers as Ronald Reagan (who proposed to his wife Nancy here), Frank Sinatra, Alfred Hitchcock, James Stewart and Groucho Marx. It closed in 1995 and its contents were auctioned off shortly after this film used it as a location in 1997. The building has since been demolished.
Included among the American Film Institute's 2000 list of the 500 movies nominated for the Top 100 Funniest American Movies.
The final feature film produced by Rysher Entertainment, which would later shut down in 1999.
