wrong trivia info

Just to let you know that in the trivia portion of Michael Gambon this was placed (In his opening lines as Headmaster Albus Dumbledore, (in 2004's "Harry Potter and the Prisoner of Azkaban", Gambon referred to "...Professor Grubbly-Plank...." and "...*his* remaining limbs...."; however, in the books (and in 2007's "...Order of the Phoenix", the character is revealed to be **female** (Professor Wilhelmina Grubbly-Plank, as played by actress Apple Brook).) This is wrong he is not talking about Professor Wilhelmina Grubbly-Plank. She doesn't show up until the 5th movie. He is talking about Professor Kettleburn who is male.

Thank you.
