"This Superman is quite mature," Bomer said about the relationship between Lois and Clark. "It’s like the battle of control freaks; he’s very protective of her; he fears for her future if their relationship ever goes public. He also has this paternal instinct towards Supergirl; plus Braniac is a weighty foe."
Superman Unbound screenwriter Bob Goodman says, “Geoff Johns gave a really great highway and it gave us an opportunity to find some roads like Clark’s relationship with Lois.” On the subject of Lois Lane Goodman told a fan, “I wrote what I thought she was, I think Lois is one of the best characters ever. I think she’s the strongest character in this movie.”
