Hurt Locker producer Nicholas Chartier isn't the only person disinvited to Sunday's Academy Awards: Sacha Baron Cohen has also been dropped from the ceremony due to what his rep calls "creative differences."Avatar spoof in which Baron Cohen would appear as a female Na'vi pregnant with James Cameron's love child, according to New York Magazine's Vulture blog. Worried that Cameron would be offended by the sketch, ceremony producer Bill Mechanic nixed the idea and bumped Baron Cohen altogether, Vulture reports."I hate to use the term because it's so ubiquitous, but there were 'creative differences,'" Baron Cohen's rep, Matt Labov, said in a statement. "Nothing acrimonious, but both sides felt that since they couldn't agree, he might as well remain in London."E!. "The Oscars are a celebration of movies... even the gaffes and out-of-bounds stuff are all part of the fun."Calls and e-mails to the Academy were not immediately returned.The 82nd Academy Awards airs Sunday at 8/7c on ABC.
