Okay here it is. It's from Guitar World from January. He's talking about his transformation and the life mask he used. I thought it was so interesting because he rarely talks about his personal life.
"When the film came out, I took my daughter who was then six years old, to see it. That probobly wasn't a great idea because the film was so long and she was so young. But at the point where my transformation scene came about, the theater was quiet, except for this little voice that cried out,
"That's not my daddy!" (laughs)
I thought that was so interesting and sweet, also as being a daughter who has watched her father act before on stage.
