On the subject of the villain in Superman: The Man of Steel:
I think it would certainly be interesting, I think there are a lot of things you could do with Brainiac. He's been given a lot of power and a lot of different abilities over the years in the comics, as far as I understand. I know that DC is working on a Brainiac storyline that they are excited about and I think combining the two and have that flow between the comics and the movie would be a nice thing. I honestly think there are a lot of interesting things you can do with Brainiac. Controlling people, controlling technology, a lot of cool things.
Routh also discussed the idea of the movie being darker compared with Superman Returns:
I don't know, I don't think the character necessarily has to be darker, I think he is kind of dark in a sense, emotional dark, in Superman Returns, and the movie as a whole was slightly dark, they could have had more prowess in it I suppose, and I think that's one thing that can be done in the sequel, so I don't know how much darker you want to make it necessarily. You make the stakes higher, you make the villain darker, I think that's a way to do it. But I don't think Superman himself needs to be darker. He definitely has to struggle, how does Superman be a part of the world? And does he have to make sacrifices to be a part of that world? To fit in and what purpose does he really play in the world? Those are all kind of dark places to explore. But, I don't think Superman should ever be dark and brooding, that's not is nature. And that's now what people what to see. Like Brainiac or something like that, a situation when the villain is...
