Harry Potter and the Prisoner of Azkaban

This third Harry Potter film is the best one yet. Director Alphonso Cuaron (Y Tu Mama Tambien, A Little Princess) has taken over from Chris Columbus and has stuck less slavishly to the original JK Rowling Books.

Daniel Radcliffe, Rupert Grint and Emma Watson are back as Harry, Ron and Hermoine, with Hermoine in particular getting to do a lot more. There are less Quidditch matches, and more menace, in keeping with the improved complexity of Rowling's third novel. Hogwarts is not safe, Draco Malfoy is no longer a menace, but just a pain in the ass. And the new CGI-scripted character Buckbeak the Hippogriff (half eagle, half horse) looks fantastic and has personality.The kids are all supposed to be thirteen but look older - hey we'll forgive them. Neville Longbottom has lost so much weight he's almost unrecognisable.

Great performances from Emma Thompson hamming it up as the ditsy professor of foretelling, Prof Trelawny, Michael Gambon as the new Professor Dumbledore (not as magical but good), David Thewliss as Prof Lupin, and Gary Oldman as the Prisoner of Azkhaban.Thrilling, complex, menacing, ****/***** stars.
