Welcome to the latest edition of Defamer Attractions, your regular Friday guide to another oversaturated summer weekend of new movies. While The Dark Knight sets up Batcamp for another week at number one, another brooding franchise goes up against Team Apatow in the also-ran camp. A British classic gets a fine art-house face-lift, meanwhile, and a windfall of new DVD's will keep the agoraphobes among us busy for a while. As always, our opinions are our own, but they're bulletproof, so read on for the only filmgoing advice that matters. WHAT'S NEW: The primary competition for The Dark Knight's second weekend will be... itself. You have to feel for Sony and Fox for dropping Step Brothers and X-Files: I Want to Believe opposite History's Greatest Film, but that's just the kind of extraordinary season it's been. Those films will perform decently enough, though — roughly $30 million for the Judd Apatow-produced Ferrell/Reilly comedy, $21 million for the sci-fi franchise adaptation — which is another bummer for Fox, which has only its overachieving The Happening to show for a long, lean summer at the box office.Also opening this weekend are the concert/protest film CSNY: Deja Vu; the oversexed '60s groupie chronicle Eight Miles High; Nanette Burstein's controversial pseudo-doc American Teen; the small-town gardener doc (seriously) A Man Called Pearl; and Minnie Driver's middling psychological drama Take. THE BIG LOSER: Not so much a "loser" as a handicapping interest of ours, Christian Bale's reported mum-thumping exploits — however blown out of proportion the actually are — could drop The Dark Knight a few percentage points more than it otherwise would have. But even if plunges by 50% (which it won't), it'll still nab $80 million, so again, save your pity for Fox.
