Warner Bros’ announcement that the sequel to Man of Steel will be a Batman/Superman team-up is big news. But it is also a totally natural development, one that has been rumored and desired for years. Charles Roven, a producer on Man of Steel and Christopher Nolan‘s Batman trilogy, famously denied the possibility in 2011:
“That may be in somebody’s mind but right now the Batman lives in his world and the Superman lives in his world. Those stories are those stories and we haven’t thought beyond each individual picture.”
I would change the wording a bit to say “That may be in everybody at Warner Bros’ mind,” because we have seen Easter eggs that hint at a Batman/Superman crossover in many recent WB properties: Man of Steel, The Dark Knight Rises, Superman Returns—even I Am Legend and Fringe.
