Lord Voldemort:A dark wizard intent on conquering the Wizarding World and the leader of the Death Eaters. Despite being aware of the success of the Harry Potter books and films, Fiennes hadn't originally read or seen them, so he wasn't interested at first when approached to play Voldemort, but after telling his sister Martha, she convinced him to take the role. Fiennes commented on the difficulty of playing someone who is "the essence of evil," and discussed giving a humanity to Voldemort in order for him to be "deeply, truly evil", citing the character's unhappy childhood as fuel for "anger, jealousy and hatred". He and director Mike Newell were interested in exploring the character's "unexpected mood swings". Newell cited Fiennes' ability to play "a realistic and frightening villain" instead of "a simple caricature" as a reason for his casting.

Ralph Fiennes

Lucius Malfoy: Draco's father and a former Hogwarts pupil of Slytherin House. He is also a member of the Death Eaters.
