[On his Character J. Jonah Jameson in Spider-Man]
J.K. Simmons: The more I read the comics books, I thought, "You gotta have the wig, and you gotta have the mustache." And this guy's always baring his big square teeth, so I got prosthetic teeth, too.
[On if he ever considered wearing a hair piece]
J.K. Simmons: I was once counseled not to be seen without hair if I waned to be a leading man. So I had a piece made, and I wore it for a few auditions, but I could never bring myself to wear it in real life. I was never Brad Pitt movie-star handsome. I've always been a character actor waiting to happen.

J.K. Simmons: I would come home with my swastika tattoos because keeping them on saved twenty minutes in the makeup the next morning. I had a hard time pulling my head out of Oz, and she's said there were times when I wasn't the most fun guy to sleep with.
[On his role in The Closer]
J.K. Simmons: For a 50-year-old bald guy to even be considered as a possibility of a romantic interest is kind of fun and different.
