The collected four box office outings for the boy wizard. In 'The Philosopher's Stone' (2001), newly enrolled at Hogwarts School, Harry (Daniel Radcliffe) and his chums Hermione (Emma Watson) and Ron (Rupert Grint) have a surprise encounter with a three-headed dog guarding a secret trapdoor. They then begin to suspect that something important might be hidden beneath the school, and when they investigate it leads to an encounter with the evil wizard Voldemort (Ian Hart). In 'The Chamber Of Secrets' (2002) Potter, with chums Hermione and Ron, are back at Hogwarts. Gilderoy Lockhart (Kenneth Branagh) and Sprout (Miriam Margoyles) have joined the staff and the friends soon find that once again all is not right at the school - pupils seem to be petrified, literally, and a monster is on the loose. In 'The Prisoner Of Azkaban' (2004) Harry, Ron and Hermione have returned to Hogwarts for their third year, but there is a shadow hanging over Harry: dangerous serial killer Sirius Black (Gary Oldman) has escaped from the Wizards' prison, the Azkaban Fortress - and he wants revenge for the death of his master, Voldemort, who Harry defeated 13 years earlier. In 'Harry Potter and The Goblet Of Fire' (2005), shortly after his reunion with his best friends, Ron and Hermione, Harry is introduced to yet another Defence Against the Dark Arts teacher: the grizzled Mad-Eye Moody (Brendan Gleeson). Harry's wishes for an uneventful school year are immediately shattered when he's unexpectedly chosen, along with fellow student Cedric Diggory (Robert Pattinson), as Hogwarts' representative in the Tri-Wizard Tournament.
