Natalie Wood said that working on this film was "the most rewarding experience I had in all films, all the way around."
This was the first of seven collaborations between Natalie Wood and Edith Head. Head worked with her more than she did with any other star.
The last day of filming was also the day Natalie Wood and then boyfriend Warren Beatty ended their two-year relationship.
Unclear whether this is a bizarre coincidence or inside joke, but when the character played by Natalie Wood is taking a taxi home from the abortionist, it passes a large billboard mentioning New York Mayor Robert Wagner. Robert Wagner, of course, was also the name of Wood's former (and future) husband Robert Wagner.
