Bellatrix Lestrange: Harry Potter and the Order of the Phoenix (2007)

Bellatrix Lestrange is one of Voldemort’s most devoted Death Eater's, unrestrained in cruelty and delighting in tormenting his enemies. Helena Bonham Carter brings eccentric menace to the role, capturing her sadistic glee and unflinching loyalty to evil. Bellatrix’s combination of fanaticism and playful malice makes her a uniquely chilling villain.
