Given the time and thought Quentin Tarantino devotes to developing each of his films, it's surprising how much their subsequent DVD releases seem like an afterthought. But the writer-director says that he plans to revisit—and expand—several long-gestating releases once he's finished with the promotion of his latest movie, Inglourious Basterds.

"When I'm through with this, I can actually finish the final Kill Bill: The Whole Bloody Affair," Tarantino told reporters Sunday in a group interview in Beverly Hills, Calif.

"I need to do one thing with it, though," Tarantino said. "I'm not going to monkey around with the movie itself, but we've actually done a whole new section for the anime as the last thing [we added]. I actually wrote a much longer script for the anime section during O-Ren's revenge chapter. Remember the guy with the long hair that kills her father? It's like, what happened to that dude? Well, I wrote it and it was the biggest, most elaborate thing I wrote—her taking him down."

Tarantino said this material wasn't a separate story, but something always intended for the film—until other narratives took over, anyway. "This was when I thought Kill Bill was going to be one movie," he revealed. "So already I thought a 20-minute anime scene may be not the wisest move. So we didn't have them do it, so they were relieved they didn't have to do it because it was so big. [But] I actually showed it to Harvey Weinstein; I had the whole script written out shot for shot what it would be, so [I said], 'Harvey, this literally would make it complete. This is everything I came up with and wrote when I wrote it.' So Production IG just did it, and I just need to work with them a little bit and go over it with them—and I'll do that once this is officially behind me."

As for that long-awaited theatrical cut of Grindhouse? Tarantino admitted he's been delinquent getting that put together on DVD and Blu-ray, but said he was happy to see there was so much demand around the world for it, even without a proper home-video release.

"We've just been lazy getting around to Grindhouse, the full edition," Tarantino said. "One of the things that has been cool about that, though, is that the Grindhouse cut has actually been playing all over the world. It's becoming this thing that theaters or revival houses would have midnight shows, like in Australia or Ireland or Scotland."

"They don't want Death Proof, [and] they don't want Planet Terror," he said. "They want Grindhouse. It's one of those things that, like, in two months it's showing again [wherever] their local midnight Friday-Saturday screening is."
