What could be more entertaining than watching professional racers in motorized product placements drive around in a huge circle for hours at a time? Throw in Will Ferrell and John C. Reilly and you’ve got yourself a smash hit, as Talledega Nights took the trophy and a prize pot of almost $50 million. 

Pirates’ sugar ship has sprung a slow leak, but the cigarette boats of Miami Vice are taking on water fast — Michael Mann’s big-screen version of his 80s TV series got hit with a 60+% drop from opening weekend, so word of mouth isn’t going to get Crockett and Tubbs out of trouble this time.
The summer has not been kind to the CG-animated movie — a new one arrives seemingly each weekend only to swiftly slip down the chart, with only Cars (appropriately) pulling in Pixar figures. This week’s soon-to-be casualty is Barnyard, which should be out to pasture within a couple of weeks. And the splunking terror of The Descent crawled into fifth with fairly decent business, considering it only trickled out on about half the screens as Ricky Bobby’s Wonder Bread car. 
Next weekend produces yawns, shrieks and cries of "Too soon!" (you figure out which gets which) with: Oliver Stone’s 9/11 melodrama World Trade Center, the hacker spooker Pulse, the dancing ditty Step Up, and the kiddie superhero flick Zoom.
