Several minor characters have been removed from the film version, most prominently Peeves the poltergeist, although actor Rik Mayall was cast in the role, but his scenes were ultimately cut from the film and never released. The book's first chapter, told from the viewpoint of Vernon and Petunia Dursley, is absent from the film. Harry and Draco's first encounter in Madam Malkin's robe shop and the midnight duel are not in the film. Norbert is mentioned to have been taken away by Dumbledore in the film; whilst in the book Harry and Hermione have to take him by hand to Charlie Weasley's friends. According to Kloves, it was "the one part of the book that felt easily could be changed". As a result, the reason for the detention in the Forbidden Forest was changed: in the novel, Harry and Hermione are put in detention for being caught by Filch when leaving the Astronomy Tower after hours, Neville and Malfoy are given detention when caught in the corridor by Professor McGonagall. In the film, Harry, Hermione and Ron receive detention after Malfoy catches them in Hagrid's hut after hours; Malfoy then receives detention as well for being out of bed. The Quidditch pitch is altered from a traditional stadium to an open field circled by spectator towers.
