While filming The Fly (1986), Geena Davis was reading the novel on which this film was based. In fact, she would read it to Jeff Goldblum while he went through the hours-long process of having prosthetic make-up applied to his body. Goldblum also appeared in Lawrence Kasdan's earlier films, The Big Chill (1983) and Silverado (1985).
The breed of Edward the dog played by Bub was a Cardigan Welsh Corgi.
The film was voted Best Picture of the Year by the New York Film Critics Circle in 1988.
Geena Davis's part is actually bigger than Kathleen Turner's, though the latter is second billed, whilst Davis is third billed.
