Hollywood Reporter columnist Anne Thompson, writing under her old L.A. Weekly moniker of “Risky Business,” says that Vanity Fair cover girl Cate Blanchett “certainly…has an edge in the supporting actress category and should grab The Aviator’s one acting Oscar for her brilliant impersonation of Katharine Hepburn.” Whoa, whoa…hold up. Blanchett will win the Oscar because she does a good impersonation? Virginia Madsen’s straight-from-the-heart, soul-stirring performance in Sideways is going to lose out to Blanchett’s fluttery little Hepburn laugh (“Haaah…hahahaha!”) that everybody remembers from Bringing Up Baby and The Philadelphia Story?
