Re: What Superhero movies would you have these directors make?
Tarantino...hmm...tough one. His style doesn't really lend itself to the big colorful explosiveness generally expected from a superhero film. I'll have to give this one some more thought.
As for the other two, I could easily see either of them taking on the Punisher quite well. Perhaps Daredevil too, or similar 'street level' heroes.
EDIT: I'll just point out real quick that I hadn't seen gwynplaine's post when I posted mine, great minds think alike!
