Grindhouse Casting Confusion

From Bloody-Disgusting:

This is becoming harder to follow, and report on, than Showtime's Masters of Horror anthology. With cast being announced, dropped and then recast - the shoot being put on hold and other problems arising, I don't know how anyone could have the cast listing correct for Robert Rodriguez and Quentin Tarantino's Grind House, which hits theaters April of '07. Inside you'll learn more about the cast, like how Rose McGowan will be in both Quentin's 'Death Proof' and Robert's 'Project Terror' and how Mickey Rourke is not in the film anymore (sigh). Read on... and for gods sake, try and keep up!
