At one time, Zack Snyder and David Goyer planned on having a Man of Steel sequel prior to Batman Vs. Superman.
That all went down the tubes when Man of Steel didn't hit a billion dollars (sound familiar?).
"No," Crowe responded when asked if there was any talk about him returning for Batman v Superman. "I think once they made the decision that... Because originally, I could be completely wrong, I think there was a number of Superman movies, but I think they made the decision to go to... jump past those and go to the idea of having Batman and Superman in the same film. So no, I didn't have any discussions about that at all."
Crowe also says he hasn't seen Batman Vs. Superman.
At one point Russell Crowe stated he was interested in doing a Superman prequel Krypton movie as well. Now it seems Goyer has taken that idea to SyFy with the Krypton series.
To date, WB has yet to announce a new Superman movie, though they did just kill the character and butcher just about everything related to his mythology.
