The film was the second of three collaborations of Gilda Radner and Gene Wilder. Their other films were Hanky Panky (1982) and Haunted Honeymoon (1986). While in France to promote this film, the pair took a brief break from their professional duties and quietly married.
The film has been memorable due to its theme tune "I Just Called to Say I Love You" sung by Stevie Wonder which won the Academy Award for Best Song. The soundtrack was also composed by Wonder and also featured performances by Dionne Warwick.
Gene Wilder's most successful film as a director at the box office. Wilder performed three roles on this movie, being also the writer and lead actor. Despite its success at the box office, the movie was Wilder's penultimate film as a director, Haunted Honeymoon (1986) being his last.
While not the first movie to be given a PG-13 rating, it is the first PG-13 movie to feature frontal (but brief) nudity, by Kelly LeBrock.
