Agreed. Although it's obviously a hypothetical scenario. I'm also under the impression that he should not be doing this past age 60. Therefore I'd prefer a recast to a reboot. In which case one of the aforementioned actors might do okay. I'm not a fan of Nolan's "one-trilogy and done" mindset when it comes to comic book movies. I like going to see Iron Man in theaters so I hope they keep it up for as long as the creative juices continue flowing.
