Kevin McKidd Reveals His Key Role in HBO’s Harry Potter

Kevin McKidd and the Harry Potter Rumors

Kevin McKidd has recently responded to growing speculation about his potential involvement in HBO’s upcoming Harry Potter series. Online discussions have suggested that the actor might be in the running for the role of Arthur Weasley, a character from the beloved book series. This has sparked interest among fans, especially after McKidd left Grey’s Anatomy in May 2026, marking the end of his 18-year stint as Dr. Owen Hunt.

Although HBO has not officially confirmed any casting details for the role of Arthur Weasley, McKidd has expressed openness to the idea. In an interview, he said, “I would never say never” about playing the character. He also mentioned that being part of the franchise again would be exciting, as he was previously offered a role in the Harry Potter films.

The Origins of the Rumors

The rumors began when fans noticed that Gracie Cochrane, who will play Ginny Weasley in the new adaptation, followed McKidd on Instagram. This led to speculation that he might join the cast, possibly as Arthur Weasley. McKidd is known for his deep appreciation of the Harry Potter series, which has fueled these discussions.

It’s worth noting that Katherine Parkinson has been cast as Molly Weasley, but Arthur Weasley is not expected to appear in the first season. The initial season will focus on the events of Harry Potter and the Philosopher’s Stone, so it may be some time before the character makes an appearance.

McKidd’s Past Connection with Harry Potter

McKidd’s connection with the Harry Potter franchise goes back further than just the recent rumors. In a May 2026 interview, he revealed that David Yates, the director of the final two Harry Potter films, had considered him for a role in Deathly Hallows, Parts 1 and 2. Specifically, McKidd was offered the role of Fenrir Greyback, a werewolf character.

However, he ultimately turned down the opportunity due to scheduling conflicts. At the time, he was contracted to star in NBC’s Journeyman, and the show had not yet confirmed its return for the fourth season. As a result, the role went to Dave Legeno, who passed away in 2023.

What’s Next for Kevin McKidd?

After leaving Grey’s Anatomy, McKidd is set to begin work on a new crime drama called The Only Suspect for Red Planet Pictures. Filming is scheduled to take place throughout June 2026. In addition to this, he will direct an episode of the upcoming season of Grey’s Anatomy, showing his continued involvement with the show.

Despite his new projects, McKidd has not ruled out the possibility of joining the Harry Potter franchise. His enthusiasm for the series remains evident, and fans are eagerly watching to see if the rumors will turn into reality.
