This Steve Carell “Funny or Die” bit isn’t that far off the mark. It’s well known in Hollywood circles (and I’ve said it more than once in this column) that movie stars frequently have disproportionately large heads.

“I’ve spoken to a fair number of big-name actors and can testify that this is frequently the case,” I wrote four years ago. “Mel Gibson has a big head; ditto Kirk Douglas and Kevin Costner. (I once wrote that Costner ‘has a head the size of a bison’s.’) Warren Beatty has a fairly sizable head. So do Phillip Seymour Hoffman and Clive Owen . I don’t recall Tom Cruise‘s head being all large, however.

“There’s obviously something about having a big head that gives a person presence, power…a sense of dominance. Full disclosure: I have a big head myself.

“Big movie-star heads are a very consistent visual factor in day-to-day Hollywood life, and yet people who don’t mix it up with talent would never, ever learn of this from mainstream interviewers and columnists. I’m just saying.”
