From Wikipedia
Dirty Dancing is a 1987 American romantic drama dance film written by Eleanor Bergstein, produced by Linda Gottlieb,
and directed by Emile Ardolino. It stars Jennifer Grey as Frances "Baby" Houseman, a young woman who falls in love with dance instructor Johnny Castle
(Patrick Swayze) at a holiday resort.

The film was based on screenwriter Eleanor Bergstein's own childhood. She originally wrote a screenplay for the Michael Douglas
film It's My Turn, but ultimately ended up conceiving a story for a film which became Dirty Dancing.
She finished the script in 1985, but management changes at MGM put the film in development hell. The production company was changed to
Vestron Pictures with Emile Ardolino as director and Linda Gottlieb as producer.
Filming took place in Lake Lure, North Carolina, and Mountain Lake, Virginia
