Geoff Johns speaks plainly to fans at NYCC 2010. Solo fims are the way to go for now in terms of movies. No Avengers-type build up like Marvel Studios. What was heard:
Asked about the possibility of shared-universe [for movie] films á la Marvel, Johns said, “I’m going to speak frankly: I think our characters are bigger than Marvel’s.” He said that he’d rather spend time building each character on his or her own rather than “smash[ing] them together.”
