Act Young
At the time, Jennifer Grey was 27, 10 years older than Baby’s character. During auditions, she only had a mere 5 minutes to prove that she really could play younger, and also that she could dance. The rest, as we know, is history.
Not Intentional
Everyone recalls the famous scene where Johnny and Baby are practicing their dance number for the big night and are crawling towards one another on the floor. As it turns out, that wasn’t meant to be a part of the film! Grey and Swayze were just warming up before doing the real scene. However the director thought it was brilliant so he kept it in the film.
