Not with Sin City. Frank Miller was way overprotective with this property and never wanted to see it made into a movie. Rodriguez came along and made a short snippet of how he saw the film being done and presented it to Miller. Miller was so impressed that he worked with Rodriguez on the film and both are credited as codirectors of the finished project. If Miller was that protective and actually became a codirector, he's not going to let it become kiddiefied. If Hollywood said it was too violent to be put on the big screen, Miller would just can it and put it on a shelf rather than dumb his baby down for the Hollywood machine.
