We were just hit with major news for theHarry PotterTV show with several stars confirmed, and one of them actually constitutes an interesting bit of trivia. Since its announcement,HBO’sHarry Potterreboothas faced immense pressure and scrutiny when it comes to how it will inevitably be compared to the previous movies, especially the legendary cast that included flawless performances by Maggie Smith, Alan Rickman, Ralph Fiennes, and many more. Now, the fandom is abuzz withsix newHarry Potteractors being confirmed, all playing members of Hogwarts' staff.

This includes the confirmation of two long-rumored castings, Janet McTeer as Professor McGonagall and Paapa Essiedu as Professor Snape. However,a few otherHarry Pottercharacters who have not received nearly as much speculation as more important players in the overarching story were also announced,and as seen in the movies, all play a significant role in bringing the rich world to life. In the case of one notably detested character, the cast actor has previously provided sharp beats while playing only minor characters.

Harry Potter’s New Filch Actor Was In The Movies As A Much More Minor Character

Most Of Sir Cadogan’s Scenes Were Deleted From The Third Harry Potter Movie

Ironically, Whitehouse has appeared in theHarry Potterfranchise before, as Sir Cadogan, the stumbling and overly showy knight inHarry Potter and the Prisoner of Azkaban.Cadogan is one of the living portraits in the Hogwarts castle;following Sirius attacking the Fat Lady’s portrait trying to get into the Gryffindor common room, Cadogan briefly fills in for her as the guardian of the house’s dormitories. He generally annoys everyone by constantly changing the password and is fired from the position after he lets Sirius into the tower (who did manage to acquire the password, in this instance).

Most of this did not make it into the movie adaptation, where there is no official follow-up about the Fat Lady after she was attacked. There are a couple of deleted scenes that feature Whitehouse more prominently, showing him interacting with the students outside Gryffindor Tower and confirming to McGonagall that Sirius had made it into the common room. Although it is an interesting plot point in the book, deleting it was in favor of keeping the runtime and pacing of the movie reasonable — at least now, Paul Whitehouse has another turn withHarry Potter.
