Harry Potter and the Prisoner of Azkaban (film)/Trivia

Trivia about  includes:


 * Alternate DVD Commentary:
 * Riff Trax
 * The fansite "The Leaky Cauldron"
 * Wizard People, Dear Reader
 * The Cameo:
 * There's a portrait of a mother and a baby next to the Fat Lady's portrait. That's Alfonso Cuarón's wife (at the time; they are now divorced) and their then-newborn baby.
 * Ian Brown, of 90s British pop band The Stone Roses fame, appears for a brief moment, magically stirring his drink in the Leaky Cauldron while reading Stephen Hawking's A Brief History of Time, cementing him forever in Harry Potter fandom as "Science Wizard".
 * Casting Gag: The first time Harry sees Sirius, Harry thinks that his gaunt appearance makes him look like a vampire. In the film, Sirius is played Gary Oldman, who played the most famous vampire ever in Bram Stoker's Dracula.
 * What Could Have Been: The adult casting for the film:
 * After the death of Richard Harris, Richard Attenborough, Christopher Lee, Ian McKellen, and Peter O'Toole were each considered for the part of Dumbledore.
 * Tilda Swinton (best known as Jadis the White Witch) auditioned for the part of Professor Trewlaney.
 * Kenneth Branagh (who had previously played Professor Lockhart) was offered the director's chair.
