Luckily for us, Entertainment Weekly asked two questions of Fox concerning Speed Racer. In response to questioning about how the role came his way, Fox had this to say;
I'm a cartoon and comic book fan, and I love anime. [But] I didn't know anything about Speed Racer. I grew up without a television. So when I found out that the Wachowskis were doing Speed Racer and were interested in me for it, I immediately went on the Internet, and as soon as I saw Racer X, I was like, I think that looks like me. I kinda think I would be a good Racer X. So then I was like, Dammit, I'm going to win this role! I went and read for it, and then waited quite a while.... It was the project last spring that I was dying to do, and I would have been so incredibly disappointed if I didn't.
Over the page, and Fox was pressed to describe how he had interpreted the role of Racer-X (I won’t spoil his real identity for those who want to keep some element of surprise).
Racer X is all about mystery. And it's all about not just disguise of suit, but it's disguise of voice — he's, like, impenetrable.... Part of the fun that I had was that I got to be a badass, and work with the most insane stunt guys. I'm proud I did it all. They didn't double me. The stunt guys were like, ''We think you can do everything. Do you want to do everything?'' ''Damn right I want to do everything. I want to do everything to the point where you think it looks like crap. That's when I need you to step in and help me out.'' [During] some of it I was just dying. I would do these fight sequences in this leather thing, and the amount of sweat was extraordinary. I was coming home ultra-dehydrated.
I’m always happy when an actor of Fox’s caliber is able to pull off all her or his own stunts. So with so many seemingly in store for us, and a trailer that is nothing more than a tease, this movie is definitely one I’m hanging out for!
