Different Strokes: How I (Gulp!) Wrote, Directed, and Starred in an X-rated Movie (John Warren Wells on Sexual Behavior)
In the early 1970s, with Deep Throat and The Devil in Miss Jones rewriting film history, John Warren Wells hired on to write the script for a high-quality pornographic movie. Originally published by Dell, Different Strokes includes the remarkable script he delivered, the production diary he kept, an interview with the film's leading lady—and a 2012 afterword that puts it all into uncanny perspective. You'd better read the book; you'll probably never get to see the movie!
