Superfly the movie was a rough biography of this man
Apparently Phillip Fenty, the writer, read a series of stories in New York Magazine in the 70's about a very colorful drug dealer named Frank Lucas. This gave him the idea for the movie. You can read a very interesting article, The "Return of Superfly" by Mark Jacobson August 14, 2000. Just Google "New York Magazine" and in its search box type the word "Superfly." Scroll down and you will get the story. Check it out, Superfly fans!
