Ben Barnes responds to Harry Potter reboot casting speculation with subtle hint at Sirius Black role

Actor Ben Barnes, known for his roles in Westworld and Shadow and Bone, has once again addressed fan speculation about his potential casting in the upcoming HBO Harry Potter reboot. While he's frequently been fan-cast as Sirius Black—and even posted several “thirsty” TikToks fueling the speculation—Barnes avoided giving a direct answer when asked if he would take on the iconic role.

In a recent interview, around the 5:15 mark, Barnes expressed admiration for the Harry Potter franchise and said he would “never say never.” Still, he made it clear that nothing official has been discussed. While acknowledging fans’ enthusiasm, he emphasized that he's not currently attached to the project but remains open to the possibility.

Barnes noted that fan-casting for him as Sirius Black began years ago, with many mistaking him for a Harry Potter alum. On Reddit and TikTok, fans continue to rally behind him, with one user noting:

“Ben Barnes LOVES being fancast as Sirius Black as much as the Marauders fandom does.”

At 43, Barnes is now around the same age Gary Oldman was when he first portrayed Sirius Black in the films, making the fan theory all the more believable. Although no casting announcements have been made, Barnes’s coy response has only amplified the hope among Potterheads.

As HBO’s 2026 Harry Potter adaptation gains momentum, fans continue to keep an eye on Barnes—hoping that their fancast might soon become a magical reality.
