"Death Proof has got to be the worst movie I ever made," he admitted in a roundtable conversation with The Hollywood Reporter. "And for a left-handed movie, that wasn't so bad, all right? So if that's the worst I ever get, I'm good. But I do think one of those out-of-touch, old, limp, flaccid-d!@k movies costs you three good movies as far as your rating is concerned."
He also cited other filmmakers that he felt stayed in the game past their prime:
"I'm really well versed on a lot of directors' careers, you know, and when you look at those last five films when they were past it, when they were too old, and they're really out of touch with the times, whether it be William Wyler and The Liberation of L.B. Jones or Billy Wilder with Fedora and then Buddy Buddy or whatever the hell. To me, it's all about my filmography, and I want to go out with a terrific filmography."
