That's an interesting question. If he already has a half hour of material then it probably has a little substance to it. If I were him I'd build on that material rather than start from scratch. I guess it would ultimately depend on the studio that owns the rights to the work that's already been filmed. If it's distributed by the same company that did Grindhouse he'll probably apply the previously filmed segments. Who knows? If it's really going to happen he'll be given a budget to play with which would make these previous segments useless. I really think the Grindhouse marquee should be used for a series of quirky exploitation style films "kind of like National Lampoons except for violence and gore ridden cheese balls". I didn't care much for Grindhouse when it was released, but it has grown on me quite a bit. I still don't care for Death Proof, but I'm actually a pretty big fan of Planet Terror at this point. I thought both films together were a bit much, but after the split I have an easier time watching them. I could see Planet Terror as a cult classic twenty years from now. I think a series of Grindhouse films that are zany like Troma movies with bigger budgets for effects and things could really catch on if given the chance...
