An Internet survey by Blockbuster Inc. found that Brad Pitt (despite the dismal showing of his "Meet Joe Black") was the actor most fans wanted to find under their mistletoe. He edged out current Sexiest Man Alive Harrison Ford by just one point, 16 to 15%. Among actresses, Cameron Diaz, who this week was named Best Actress by the New York Film Critics for her role in "There's Something About Mary," easily topped the list with 23%. Runner-up Julia Roberts mustered only 16%.
