The National Organization for Albinism and Hypopigmentationare is launching a campaign against the Tom Hanks film of "The Da Vinci Code." NOAH had unsuccessfully asked film director Ron Howard to change author Dan Brown's "hulking albino" character Silas, The New York Post reported Sunday. A California teacher who is albino wrote to Brown in 2003 voicing her concern over the "hateful" stereotypes assigned to albinos in literature and film, the newspaper said. Brown swiftly replied, writing: "You might be interested to know that Silas ... is a far more sympathetic character than anyone else in the novel." Details of the NOAH campaign against "The Da Vinci Code" and Hollywood's history of "evil albinos" were not spelled out.
