“Law & Order: SVU” is taking on all the headlines this season. I can tell you exclusively that the show already has a script ready to shoot about the saga of former IMF leader Dominique Strauss-Kahn and his alleged rape of a New York hotel maid. The names will be changed but the details will be pretty easy to follow, according to sources. This news comes on the heels of a prior announcement that “SVU” will also do a show based on Maria Shriver and Arnold Schwarzenegger. According to my “Law & Order” sources, the show will be doing a lot of these this season since “we’re the only Law & Order left on the air.” The show is also soldiering on without Chris Meloni, who couldn’t make a deal with Dick Wolf for another season. We’ll see how that works out. Mariska Hargitay made a last minute deal, B.D. Wong has left, and former DA’s played by Stephanie March and Diane Neal are returning. There are also new cast members. “It will be a different show,” says a source. Meloni, meantime, goes on to the new “Superman” movie. The good betting is he’ll be heading up his own TV series by fall 2012 or spring 2013.
