To be honest, I don’t want a prequel. I rather want a new movie. It would be like another director these days in Hollywood and cash in on what is already there with sequels and prequels. But that’s just me. Plus according to QT, he has about 10+ years left to direct movies, so I want as many new ones as possible.
I don’t think QT will ever quit. Guys like William Wyler, Bette Davis, Joan Crawford, Billy Wilder, etc, etc. died doing what they loved best. Hell, Robert Altman died a little after finishing his movie with PT. I think he loves the sweat too much to quit that soon.
