First of all it’s really based off 91/2 weeks. That movie came out in 1986. 91/2 weeks is based off a book of the same name and it is a true story. The book 91/2 weeks is different from the movie. The movie is Hollywood the book is a true story which is a dark book. 91/2 weeks way better than 50 shades of grey it copied 91/2 weeks which came out in 1978. Truth be told nobody in this world ever changes who they really are.
