Last week I mentioned the Lazarus Pit as an example of a comics staple that Batman movies — any Batman movies, arguably — would probably be reluctant to use. While the Pit comes with certain restrictions and side effects, it still boils down basically to an unlimited supply of extra lives. It runs counter to the idea of Batman as being grounded in reality, but in the context of a shared universe where Batman pals around with extraterrestrials (and their agents), a super-powered Amazon, and the King of Atlantis, it’s not that far-fetched. This is the old “Character Y could solve Character X’s problems” hypothesis, and it tends to be met with “Character X and Character Y play by different rules.” A good example of the latter was a “No Man’s Land” story featuring Superman (coincidentally collected in the new NML Vol. 3), where the Man of Steel’s well-intentioned assistance in trying to rebuild an earthquake-devastated Gotham turned out to be exactly wrong under the circumstances.
