In his third year at Hogwarts, Harry (Radcliffe) is haunted by news that the man who betrayed his parents, Sirius Black (Oldman), has escaped from Azkaban prison. This threat taints his usual adventures at school with buddies Ron and Hermoine (Grint and Watson). And as time ticks away, this heroic teen trio must draw on unknown strengths to get through it. They're helped (or hindered) by the school faculty: a new professor with a dark secret (Thewlis), the burly and put-upon Hagrid (Coltrane), the knowingly mischievous headmaster (Gambon), the sinister Snape (Rickman), the ditsy divinations teacher (Thompson) and so on.

Cuaron gets the tone exactly right. Unlike the over-lit, precious design of the first two films, he darkens and desaturates everything, combining a cheeky sense of humour with moments of strong comedy and real suspense. The magical world is much more offhanded--amazing things happen around the edges of the screen, but they're mere details that add to the story, not the main focus. And this lets the set pieces come to life much more vividly, from Harry's outrageous journey across London in the Knight Bus to his encounter with his ferocious Monster Book of Monsters. Even the Quiddich match is something different--here played in a raging thunderstorm while fearsome Azkaban guards prowl the clouds.

This shift puts characters more central and makes the plot more coherent. Cuaron discovers three excellent young actors in the central roles; nothing in the first two films suggested that Radcliffe, Grint and Watson could deliver such solid performances as they do here! There are some moments that take the breath away, most notable are the delicate scenes between Radcliffe and Thewlis. And the stellar supporting cast also find untapped shadings in their characters.

An emphasis on character and story over gimmicks also gives the animals and computer generated characters much more life and personality. Harry's owl Hedwig and especially Hagrid's doomed hippogriff Buckbeak actually have authentic emotional life. Meanwhile, the settings are reimagined in service of the story--from the crumbling edges of Hogwarts to a general messiness in hair and costumes, all of which adds texture and mood. This is not only funnier, more imaginative, more exciting, sexier and scarier than the previous two Harry Potter films, it's one of the best kids' movies of the year.

Karol, London: "A thoroughly enjoyable film which brought me to tears and made me laugh (although the comedy moments went above the heads of the children in the audience). Fantastic adaptation of the book - choosing the right material to include and omitting the unnecessary. Go see!" (7.Jun.04)
