I’m not making even a moderate-sized deal out of this, but as I sat in the front row during yesterday’s Cafe Society press conference I was noticing that Kristin Stewart, who exudes something truly luscious in the film, has a noticably smaller head than Woody Allen or costar Blake Lively. The general myth is that most big stars tend to have big heads, but there are always exceptions. Stewart, who’s been in a good career groove since her Cesar-winning performance in Clouds of Sils Maria, is simply more modestly proportioned.

He said that Silver told him, “Dan, all big stars have really big heads.” Physically, he meant.

“I’ve spoken to a fair number of big-name actors and can testify that this is frequently the case. 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 [did] Phillip Seymour Hoffman. I would say that Clive Owen certainly qualifies. And yet I don’t recall that Tom Cruise‘s head is all that large.

“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.”
