Magical creatures in Harry Potter Granger's pet cat. Crookshanks was purchased by Hermione in a shop called Magical Menagerie in the third Harry Potter book; Harry Potter and The Prisoner Of Azkaban. Crookshanks resembles a Persian Cat, and Rowling has described him as half-Kneazle, an intelligent cat-like creature sensitive to dishonesty, explaining his identification of the rat 'Scabbers' as Peter Pettigrew, and of Sirius Black in his dog form. Crookshanks is seen in Prisoner of Azkaban talking to Padfoot in the school grounds. Crookshanks was portrayed by a cat called Crackerjack. Dobby is a "house-elf" in the Harry Potter series. He was once owned by
Harry Potter (film series) for the third film, "Harry Potter and the Prisoner of Azkaban", claiming he was "burned out". He moved to the position of producer, while Alfonso Cuarón was approached for the role of director. He was initially nervous about directing the instalment since he had not read any of the books or seen the films. After reading the series, he changed his mind and signed on to direct since he had immediately connected to the story. Because Cuarón decided not to direct the fourth instalment, "Harry Potter and the Goblet of Fire", a new director had to be selected. Mike Newell
