Helena Bonham Carter's Bellatrix Lestrange ranks among the best villains in the "Harry Potter" franchise. She's one of Lord Voldemort's (Ralph Fiennes) most loyal disciples, and she's arguably even more sadistic than He Who Must Not Be Named, which is evident by the way in which she gleefully torments her victims. These days, it's difficult to imagine anyone other than Carter in the role of Bellatrix. Be that as it may, another actor was initially cast as the wicked Death Eater.
