Aaron Eckhart talks I, Frankenstein

We recently revealed that Aaron Eckhart has been cast in the graphic novel adaptation I, Frankenstein .

Seems the actor is now getting a bit jittery about what he's signed himself up for.

"Somebody says, 'Do you want to play Frankenstein?' and I was like, 'Well, I haven't thought about it," Eckhart joked to Coming Soon.

"Then I read the script. Whenever you read a script that you want to do, you start feeling yourself in that character. All of a sudden your juices start flowing. That's how you know you should do a movie. Now I'm gonna be Frankenstein and I'm kind of worried about it, actually. I've gotta go and figure out how the hell I'm gonna play Frankenstein."

Eckhart also confirms he'll be spending plenty of time in the make-up chair undergoing a transformation into the creature. Don't count on those trademark bolts, though.

"I think bolts came later. I'm not finding bolts in Mary Shelley's Frankenstein . I think all that sort of stuff is an invention of Hollywood. I don't know where it came from,” Eckhart said.

“Even the lightning isn't a big part of [ her book ]. Frankenstein the book deals more with the subjective. The feelings of the creature and less about the making of."

I, Frankenstein begins filming in Australia in January 2012 and opens 22 February 2013.
