Harry Potter and the Order of the Phoenix (movie)
Another school year at Hogwarts begins. A new teacher, Dolores Umbridge, has been appointed to work at the school by the Ministry of Magic to make sure that the school does not discuss Voldemort's return. Professor Umbridge bans the use of defensive spells and refuses to teach the students how to protect themselves from evil magic. Frustrated, Harry Potter and his friends, Ron and Hermione create a secret club named "Dumbledore's Army". Many other students join Dumbledore's Army and they learn defensive spells together.
