Tarantino's segment, Death Proof, was lengthened for showing at the Cannes Movie Festival. Most of the film's scratches (used in Grindhouse) were also cut out.
Grindhouse was only released as one movie in English speaking countries. In other countries, the movie was cut in two parts (Tarantino and Rodriguez segments), but each one is an extended version of those seen in the one shot movie.
In Death Proof, after Zoe flies off the hood, she walks back to the car and says, "Phew that was a close one". In the Unrated Extended version it then cuts right to her line, "So, where's the maniac?" In the U.S. Theatrical Double Feature version there's some extra lines of dialog in between: As Zoe notices that Abernathy and Kim have been crying she remarks, "You guys look like shit. Who died?" Abernathy then asks Zoe if she's okay, to which she replies, "Well, I'm gonna have a hell of a bruise on my bum, but aside from that I'll be sweet."
