Steve Carell refuses to be intimidated by the growing number of Hollywood superstars who are fans of his hit TV series The Office.

Carell, who plays boss-from-hell David Brent in a part made famous by Ricky Gervais in the original UK show, remains unfazed when told Brad Pitt, Ben Stiller and Madonna all admire The Office.

He jokes, "Actually I do go to sleep thinking about Brad Pitt all the time. I go to sleep thinking about him and what he thinks about me.

"I want to get any notes that he has on the show."
