In an interview done on set and published in Starlog 109 (cover date August 1986), Melanie Griffith reveals that she was pregnant with her first child when she tested for this movie. She was hired with a clause in her contract that if she did not have the baby by September 9, her role would be recast. Her son Alexander (with her then husband Steven Bauer) was born August 22, 1985, and Griffith started the film three weeks later, taking the boy along to the set each day to breastfeed him.
