I've just thought of another book and a film that I like equally.
I read Alice Walker's The Color Purple when it was first published in 1982. I read it on holiday by myself in Greece, and I found it really moving.
The film, released two years later was brilliant, but nothing like the book. All evidence of lesbianism had been removed from the story, but the cast, including a memorable performance from Oprah Winfrey, turned it into a great film, in my opinion.
I've just watched part of the film on YouTube. It's when hard drinking sinner Shug, is reunited with her preacher father. The music is by Quincy Jones, and it fills my heart with joy, and the hairs on the back of my neck stand up, everytime I watch it.
