In an interview with Vanity Fair, director Zack Snyder revealed that he had originally planned for Bruce Wayne to fall in love with Lois Lane in “Justice League”.
With Superman having died at the end of “Batman v Superman: Dawn of Justice,” Snyder had toyed with the idea… but Warner Bros. nixed the idea.
“The intention was that Bruce fell in love with Lois and then realized that the only way to save the world was to bring Superman back to life,” Snyder said. “So he had this insane conflict, because Lois, of course, was still in love with Superman. We had this beautiful speech where [Bruce] said to Alfred: ‘I never had a life outside the cave. I never imagined a world for me beyond this. But this woman makes me think that if I can get this group of gods together, then my job is done. I can quit. I can stop.’ And of course, that doesn’t work out for him.”
Snyder also revealed that hard-core fans will have their minds blown with the inclusion of a cameo which will take place in an entirely new ending the director shot for this new version of the film.
