Speaking to IGN, Man Of Steel star Henry Cavill was cautiously behind reprising the role for a Justice League or Batman/Superman movie, but agreed with Zack Snyder that Man Of Steel 2 was needed to cement the shared universe.
“Well, Justice League is in the long run,” confirmed Cavill. “I mean it’d be fun, but Man Of Steel was about a god coming to Earth and everybody getting use to it.
“Like we can’t just have a world full of gods now. Batman/Superman would be great fun, because it brings two worlds together and could introduce some new characters. But Man Of Steel 2, is a continuation of a story, and I guess we can introduce some characters in that.”
