According to a December 2008 interview with Dirty Dancing screenwriter Eleanor Bergstein, the characters of Baby and Johnny were both influenced by Bergstein's own biography. Like Baby Houseman, Bergstein came from a liberal Jewish family who visited Catskills resorts during the 1960s; her father was a doctor; and she was nicknamed "Baby" until she was 22 years old. Like Johnny Castle, Bergstein was a skilled "dirty dancer" who learned at house parties and later became an Arthur Murray instructor.
