As the guessing game continues over the actor playing Voldemort, it is clear that Ralph Fiennes, who portrayed the character in the Harry Potter movies, will not reprise his role in the TV show. 

Who will play Voldemort in the Harry Potter TV series?

Amid the secrecy around the star playing the role of Voldemort, media reports claim that it is deliberate strategy of the makers. The decision echoes the character’s 'He Who Must Not Be Named' tagline, reinforcing the aura of mystery and fear surrounding Voldemort’s identity. 

Meanwhile, the rumors circulating on the internet have provided two names, who could be the perfect fit for the role. The character could be convincingly portrayed by either Matt Smith or Cillian Murphy, according to fans. 

The Oscar-winning star was particularly the pick between the two, which even Fiennes approved. Previously, it was reported that Murphy was roped in for the character of Professor Quirrell.

Though no confirmation was given by the Warner Bros. Studios, the CEO, Channing Dungey, said, “We’re still weighing a couple of different options there, so we’re not quite ready there yet. That’s an important role to get right.”

Later, it was confirmed that the role went to Luke Thallon.

The Harry Potter TV series was announced first in 2023, and since then, the fans have been excited over the wizard story returning to the screens. Earlier this month, HBO released the first looks of Harry Potter and Rubeus Hagrid, portrayed by Dominic McLaughlin and Nick Frost, respectively.
