I’m no joker: the Warner Bros comic book caper achieved this domestic gross milestone Saturday on its 30th day of release.  As of Sunday, The Dark Knight‘s North American cumulative stood at $$471,493,000, ahead of Fox’s Star Wars (incluing all re-releases) with $460,998,007. No. 1 is still Paramount’s Titanic with $600,788,188. Of course, none of these totals are adjusted for inflation, or higher ticket prices, or number of tickets sold, etc. This weekend, the latest Batman installment was knocked out of No. 1 after 4 straight weekends as the top movie at the box office. It finished #2. For the full weekend b.o. report, see my ‘Tropic Thunder’ Rumbles Box Office; ‘Dark Knight’ #2, ‘Clone Wars’ #3.
