Zack Snyder's Man Of Steel differs from previous screen incarnations of the character in quite a few ways, but probably most significantly in the Clark/Lois relationship. In this movie Lois knows where Supes hangs his cape, and at the end when Clark starts work at the Daily Planet she is obviously perfectly aware of his new "secret identity". So where does this leave their dynamic in the next movie? io9 asked Henry Cavill what he thinks about the fact that Lois knows Clark's secret moving forward.
"I think it's essential. Because if we're trying to base it reality, there's no way that Lois has these direct interactions with Superman, and then doesn't recognize Clark sitting next to her in the office. If she falls in love with Superman, and she's ignoring a guy who looks just like Superman, behaves just like him, and has the same kind of mannerisms and behavior, then what does that say about Lois? I like this relationship. She saves him just as much as he saves her."
Cavill adds that although the final few minutes of
Man Of Steel may have been lighter in tone to the rest of the movie, doesn't mean we should necessarily expect that to carry over to the sequel. He says that we might get some "gallows humor", but that
"when it comes to something like a threat to the planet, and people that he loves, it's not necessarily something you want to take lightly.". More at the link below.
