The box office went ape for King Kong over the weekend... oh, right that's next Monday's news. (Hey, I didn't want to be the last hack to make a lame joke about people being driven bananas by Peter Jackson's instaclassic.) This weekend, The Chronicles of Narnia: The Lion, the Witch and the Wardrobe dominated the cineplex, conjuring up $67.1 million in receipts. Expanding nationwide after two weeks, George Clooney's muy political Syriana took in $12 million for a second-place finish. But the big story no, I'm not going to make another pathetic Kong crack is the performance of two flicks in limited release: Memoirs of a Geisha, playing on only eight screens, made a stunning $674,000; and Brokeback Mountain the movie of the year according to the L.A. Film Critics Association and the Boston Society of Film Critics wrangled $544,549 in just five theaters. Its $108,910 take per screen is the highest per-showing average for any adult drama in history, not to mention the highest per-showing average for any adult drama that redefines the term "cowpoke."
