Harry Potter and the Prisoner of Azkaban DVD+Blu-ray

The Harry Potter franchise takes a turn for the darker side in the latest cinematic instalment of JK Rowling’s hugely popular series, here helmed by Y Tu Mama Tambien director Alfonso Cuarón.

This third instalment sees Harry (Daniel Radcliffe), Ron (Rupert Grint) and Hermione (Emma Watson) return 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. For Harry's protection, Azkaban has sent an army of soul-sucking Dementors to guard Hogwarts from a possible attack by Black - but they turn out to be as much of a threat to Harry as Black himself. As myth, magic and teenage hormones combine to weave their dark spell, Harry uncovers a few more crucial secrets about his mysterious past. The supporting cast includes Emma Thompson, Michael Gambon, Alan Rickman, Julie Walters, Maggie Smith, Robbie Coltrane, David Thewlis and Timothy Spall.
