Olivia Newton-John was our first choice to play Sandy, but she was nervous about acting, whether she would feel comfortable with us and could pull it off at all.
It was very unusual, because normally the producer requests the test to determine whether they want to hire someone or not. Olivia was concerned about playing a seventeen year old.
As we went into production, there was no song for Olivia and no idea where we would put it. It was not even on the production schedule.
