Jim Carrey Relishes The Fun Of Returning To Dr. Robotnik In Sonic The Hedgehog 2

In your career, you've played some very sweet, but dumb characters, like in "Ace Ventura" and "Dumb and Dumber." In "Sonic," you're playing an evil genius. Do you have a preference, smart and evil or...?

I think smart and completely dumb are essential parts of my character in life and they assert themselves individually from time to time. Sometimes, you do things in your life and you think, "Well, maybe I'm a pretty smart animal," and then there are other times you go, "No, I haven't learned a thing." [Laughs] It's a great thing to be able to play the spectrum, and to be thought of that way is wonderful.

I had to dumb it down a little bit to play a guy with a 300 IQ, but ... This character's so much fun, and he's the contrast to Sonic. The important thing about this movie is that Sonic is that preteen innocence and lack of skepticism that enjoys everything that's happening in the zeitgeist going past. He goes, "Oh, I want to play with that, and I want to play with that." He's not afraid of a damn thing.

Through this movie, families, parents get to look and remind themselves of what it was like to be that way. The kids, they get to see this wonderful, innocent energy winning against this scary monster. I hope they get laughs. I'm in the movie to give parents something to do as well as make the kids laugh. I try to have my stuff mean more than one thing every once in a while. [Laughs]
