<P> Voldemort appears in seven Harry Potter films, namely Harry Potter and the Philosopher's Stone, Harry Potter and the Chamber of Secrets, Harry Potter and the Goblet of Fire, Harry Potter and the Order of the Phoenix, Harry Potter and the Half - Blood Prince, Harry Potter and the Deathly Hallows--Part 1 and Harry Potter and the Deathly Hallows--Part 2 . Several actors have portrayed him in his varying incarnations and ages . </P> <P> In Harry Potter and the Philosopher's Stone, Voldemort's manifestation is as a face on the back of Quirrell's head, an effect achieved by computer generated imagery . Ian Hart, the actor who played Quirrell in the same film, provided the voice and the facial source for this character . Voldemort also appears in a scene in the Forbidden Forest where he is seen drinking the blood of a unicorn . As Voldemort's face was altered enough by CG work, and Hart's voice was affected enough, there was no confusion by Hart's playing of the two roles . In that film, he was also shown in a flashback sequence when he arrived at the home of James and Lily Potter to kill them . In this scene Voldemort is played by Richard Bremmer, though his face is never seen . His next appearance would be in Harry Potter and the Chamber of Secrets as the 16 - year - old Tom Marvolo Riddle (portrayed by Christian Coulson). </P> <P> In Harry Potter and the Goblet of Fire, Voldemort is initially only heard, possessing the scratchy, weak voice heard in the first film . By the film's climax, however, he appears in his physical form for the first time, played by Ralph Fiennes . As in the book, Voldemort is shown clad in dark black robes, being tall and emaciated, with no hair and yellowish teeth; his wand has a white tone and the handle appears to be made of bone; his finger nails are long and pale blue while his toe nails appear to be infected . Unlike in the book, his pupils are not cat - like and his eyes are blue, because producer David Heyman felt that his evil would not be able to be seen and would not fill the audience with fear (his eyes do briefly take on a snake - like appearance when he opens them after turning human, but quickly turn normal). As in the book, the film version of Voldemort has snake - like slit nostrils with the flesh of his nose significantly pressed back . Ralph Fiennes' nose was not covered in makeup on the set, but was digitally removed in post-production . In this first appearance, Voldemort also has a forked tongue, but this element was removed for the subsequent films . </P> <P> Fiennes stated that he had two weeks to shoot the climactic showdown scene where he is gloating over a terrified Harry, played by Daniel Radcliffe . Fiennes said with a chuckle: "I have no doubt children will be afraid of me now if they weren't before ." In preparation, he read the novel Goblet of Fire, but jokingly conceded: "I was only interested in my scene, and I had to go through thousands and thousands of other scenes which I did, dutifully, until I got to my scene and I read it many, many, many, many, many times and that was my research ." Fiennes reprised his role as Voldemort in Harry Potter and the Order of the Phoenix and Harry Potter and the Deathly Hallows--Part 1 and Part 2 . </P>
