Warner Bros.' upcoming superhero adventure Batman Vs. Superman is far more than a straight-up sequel to last year's Man of Steel, introducing a number of characters into this universe, such as Batman (Ben Affleck), Wonder Woman (Gal Gadot), Lex Luthor (Jesse Eisenberg) and Bruce Wayne's faithful butler Alfred (Jeremy Irons). The man responsible for bringing these icons together on the page is screenwriter David S. Goyer, who recently spoke about balancing several famous characters in one movie, and the pressure to get each one right.

"I always try my best to honor every character. When you're dealing with big iconic characters, there's a lot of fan pressure to get it right, and I respect that and admire that passion enormously. At the same time, you can't let your creative process be too crowded by that or distracted by it. It's not always one uniform opinion of how you should portray this character or that character. I think I've done a pretty good job of walking that razor's edge. You just have to do your best and know what's out there, but at the same time, follow your own muse."

We reported in December that Oscar-winning Argo screenwriter Chris Terrio was brought on to rewrite the script, but it isn't known how much the story will change between his draft and David S. Goyer's script.

Zack Snyder is directing this highly-anticipated sequel, which starts production this spring. The cast also includes Man of Steel stars Henry Cavill (Clark Kent/Superman), Amy Adams (Lois Lane), Diane Lane (Martha Kent) and Laurence Fishburne (Perry White).
