Trivia: In the scene where Johnny and Baby practice dancing, and she keeps laughing when he runs his arm down hers, it was not part of the scene, she was actually laughing and his frustration was genuine. They left it in the movie because it was effective. Baby falling over in this scene was unplanned too.
Trivia: In the famous scene where Johnny and Baby crawl towards each other on the floor, Swayze and Grey were messing around while warming up to do the real scene, but the director liked it so much he kept it in the film.
Trivia: In the scene where we first see Patrick Swayze dancing, the older lady dancing with him is both the choreographer and the woman whose life the movie plot is based on.
Suggested correction: It's based on Eleanor Bergstein's life. Not Miranda Garrison's. (Who originally stepped in to the role vacated by Kelly Bishop at the last minute).
Trivia: My aunt has stayed at the resort where the movie was set, and she lives around there. Apparently the crew spray painted the trees green because it wasn't really summer.
