The news of Hoult’s casting in the second season of HBO’s Harry Potter adaptation prompted an outcry from his fans earlier this month. Hoult was set to play the conniving but charming Professor Lockhart in the upcoming season, but many fans were dismayed by the actor’s decision given author JK Rowling’s repeated social media attacks on the transgender community. As a result, any of the Skins star’s biggest fans, including those with accounts dedicated to charting his successes, announced they would no longer be supporting him. It has now been reported that Hoult will be exiting the wizarding world due to ‘scheduling conflicts’. Instead, the Game of Thrones star has been named as his replacement to play the eccentric wizard, Variety reports.

A self-professed Harry Potter fanatic, Harington has said he fell in love with Rowling’s books as a child and has re-read them several times since. He previously told Variety that taking on the role of Lockhart for the Harry Potter and the Chamber of Secrets audiobook was an easy decision. ‘It was a really simple yes, because I love the character,’ he said. ‘As far as cameos in a series go, you don’t get much more entertaining and fun to do as an actor than Gilderoy Lockhart. It was a no-brainer.’ {"@context":"https:\/\/schema.org","@type":"VideoObject","name":"Harry Potter and the Philosopher's Stone HBO Series Teaser Trailer (2026)","contentUrl":"https:\/\/videos.metro.co.uk\/video\/met\/2026\/03\/25\/4037780136655277829\/480x270_MP4_4037780136655277829.mp4","description":"A new era of Hogwarts begins.

But the criticism around the show doesn’t show any sign of slowing down, with several of the actors involved facing questions about their stance on trans rights as a result.
