Why the chrome dome, Jack?

Is Jack Nicholson playing Lex Luthor in the next “Superman” movie? Maybe he’ll be Daddy Warbucks in a remake of “Annie.” Or perhaps he’s going for the same hairstyle as Britney Spears.

Turns out the shaved head he sported at the Academy Awards on Sunday night was just devotion to craft.

Nicholson and costar Morgan Freeman are filming director Rob Reiner’s film “The Bucket List,” a buddy comedy/drama about two terminally ill men who flee a cancer ward to complete a list of things they want to do before they die. It is scheduled for release in November.
