From his Q & A with Paul Goat Allen for The Barnes & Noble Book Blog:
I have to be honest, Brandon. I’m not a big fan of superhero fiction—but Steelheart blew me away. I described it as a “mind-blowing” experience. Do you recall where the original seed of inspiration for this novel, and series, came from?See: My Book, The Movie: Brandon Sanderson's "Mistborn trilogy."
That’s very cool to hear! Approaching this book was in some ways very difficult for me because I have read superhero prose, and it usually doesn’t work. I came to it with some trepidation, asking myself, “Is this really something you want to try?” A lot of the superhero tropes from comic books work very well in their medium and then don’t translate well to prose. So for my model I actually went to the recent superhero films. Great movies like The Dark Knight or The Avengers have been keeping some of the tropes that work really well narratively. Tropes that feel like they’re too much part of tradition—like putting Wolverine in yellow spandex—work wonderfully in the comics. I love them there! But they don’t translate really well to another medium.
I think part of the problem with superhero fiction is that it tries to be too meta. It tries very hard to poke fun at these tropes, trying to carry them over into fiction, and it ends up just being kind of a mess. But the genre has translated wonderfully well to film through adaptation. So when I approached Steelheart, I actually didn’t tell myself, “I’m writing a superhero book.” In fact, I’ve stayed very far away from that mentally and said, “I am writing an action-adventure suspense-thriller.” I use some of the seeds from stories that I’ve loved to read, but really, Steelheart is an action thriller. I used that guide more than I used the superhero guide. I felt that adaption would be stronger for what I was doing. Comic books have done amazing things, but I felt this was what was right for this book.
As for the original seed that made me want to write this story, I was on book tour, driving a rental car up the East Coast when someone aggressively cut me off in traffic. I got very annoyed at this person, which is not something I normally do. I’m usually pretty easygoing, but this time I thought to myself, “Well, random person, it’s a good thing I don’t have super powers—because if I did, I’d totally blow your car off the road.” Then I thought: “That’s horrifying that I would even think of doing that to a random stranger!” Any time that I get horrified like that makes me realize that there’s a story there somewhere. So I spent the rest of the drive thinking about what would really happen if I had super powers. Would I go out and be a hero, or would I...[read on]
