Trivia[]
In his debut appearance, Alastor Moody doesn't appear until the end of the fourth book and the film adaptation, due to him being impersonated by Barty crouch Jr in the entire story.
In the book version of The Order of the Phoenix, Moody gave Harry the picture that had his parents James and Lily as well as the first incarnation of the Order of the Phoenix and explained who each of the members were. However, it was changed to Sirius in the film adaptation of the fifth film for unknown reasons.
