As HBO’s Harry Potter reboot progresses through production, fans remain eager to discover who will embody the villainous Voldemort. Speculation has frequently connected Oscar winner Cillian Murphy to the role, with strong support from loyal Wizarding World fans and even Ralph Fiennes, the original actor behind the dark wizard. Recently, Murphy spoke publicly for the first time about the rumors surrounding his potential casting as Voldemort in the reboot.
During an appearance on the podcast Happy Sad Confused, Murphy was asked whether he had been approached to play Voldemort or was involved in the project in any way. He replied,
No. I mean, genuinely. I mean, my kids show me it occasionally, but like, I don’t know anything about that,
—Cillian Murphy
He went on to praise Ralph Fiennes’ previous portrayal, acknowledging the challenge inherent in following such a celebrated performance:
I mean, also, it’s just really hard to follow anything Ralph Fiennes does. The man is an absolute acting legend. So, good luck to whoever is going to fill those shoes.
—Cillian Murphy
The Challenge of Following Ralph Fiennes’ Iconic Voldemort
Murphy’s refusal to confirm his involvement echoes similar sentiments from other actors linked to the reboot. Notably, Matt Smith, star of House of the Dragon, ruled himself out of consideration for the role last month, citing how challenging it would be to succeed Ralph Fiennes. Both actors’ remarks reveal a deep respect for Fiennes, whose chilling and memorable performances helped define Voldemort for millions worldwide.

The Harry Potter film series from 2001 to 2011 left a lasting mark on pop culture, partly due to the perfect casting of its characters. Fiennes’ Voldemort became a reference point for the villain, making it difficult for any new actor to avoid comparison. His depiction contributed significantly to the films’ enduring popularity and cultural resonance.
Adding to the challenge for the reboot, the original films set a high standard not just in acting but also through their distinctive visual style and production design. The HBO series aims to delve deeper into characters and storylines that the movies could not fully explore, thanks to the longer format of television. Yet, critics such as Chris Columbus, director of the first Harry Potter film, have expressed concern over the series’ visual direction. He questioned what the point of a reboot would be if the sets and costume designs—like those of Hagrid and potentially Voldemort—closely replicated the original films.
What the Reboot Means for Voldemort’s Portrayal and Casting
The role of Voldemort, who fully emerges in Harry Potter and the Goblet of Fire, carries significant weight throughout the latter half of the saga. This means the actor cast shall commit to a substantial long-term project. The demanding nature of a multi-season television series may deter some established talents from taking on the role. Consequently, HBO’s reboot might cast a lesser-known actor willing to bring a fresh interpretation to the iconic villain.
Industry rumors suggest that the role of Voldemort might already be cast and deliberately kept under wraps to enhance surprise during Season 1. If true, fans can anticipate revealing the villain’s new face as the series unfolds, ushering in a new chapter for the character within the Wizarding World.
In casting Voldemort, HBO faces the complex task of honoring a beloved original performance while offering something new to long-time fans. Cillian Murphy’s comments and those from Matt Smith underscore the respect for Ralph Fiennes and the difficulty this role presents. The reboot must balance these expectations with its opportunity to expand and enrich the Harry Potter narrative for a modern audience.
