New style for Draco
The pictures also feature Draco Malfoy, played by Tom Felton, with a new, non-slicked back hair style.
Director Alfonso Cuaron has said that he's trying to make the third Potter flick feel a bit more up to date than the earlier films.
He's being replaced on the next film, Goblet of Fire, by Brit director Mike Newell, who made hit film Four Weddings and a Funeral.
Prisoner of Azkaban is expected in cinemas in June 2004.
