Will Ferrell Talks Kids, Superheroes, and Justin Bieber

What was going through your mind when you were asked to play a blue alien super-villain with an abnormally large head?

I just thought -- from the moment they showed me the artwork for it -- that this kind of semi-menacing character [was] really just a sweetheart who was totally misunderstood and ends up a good guy. And I thought that was a unique take on the good-versus-evil struggle.

If you were a real superhero what would your name and power be?

Probably Vegetable Man. Because a lot of people don't like vegetables, but I would triumph over the ostracization and hatred of vegetables to show how good they are for you. And my special power would be...I'd be able to puree any sort of vegetables just by looking at them.

Are your sons into superheroes?

They are fully into superheroes. They pretty much look at comic books every day. I just [saw] a rough cut of the movie and...one of the things I came away with was that my 6-year-old and, I think, my 3-year-old are going to love this movie. They're not going to believe I did the voice of this character.
