"For Tomorrow" would have been an interested adaptation for a Superman movie, if kind of "out there" and they would have had to drop the JLA. Still, it would have been the first time in a movie we could have gotten a look at how desperately Lois and Clark love each other. And Lois wearing the cape would have been pretty cool as well.
From the 52 series (when Clark had temporarily lost his powers).
From a late 2002 ACTION issue.
