Complete List of Actors Rumored for the Harry Potter TV Series Cast

HBO’s highly anticipated Harry Potter television adaptation is making waves as casting news emerges, stirring excitement among fans and introducing a roster of intriguing actors. Following its announcement, questions abound regarding the necessity of a new series so soon after the beloved films, which have received critical acclaim. Nevertheless, the creative team has promised that the TV series aims to stay truer to J.K. Rowling’s original novels, sparking renewed interest in this ambitious project.

Currently, the casting call is open for the iconic “Golden Trio”: Harry Potter, Hermione Granger, and Ron Weasley, roles previously portrayed by Daniel Radcliffe, Emma Watson, and Rupert Grint. This decision to seek fresh faces ensures an innovative start, affording emerging talent an opportunity to shine. With more than 30,000 young hopefuls auditioning, the series is poised to discover the perfect cast. In contrast, the selection for adult roles appears to be evolving, with a focus on well-known actors.

7 Cillian Murphy

Voldemort

Rumors are swirling around the possibility of Cillian Murphy stepping into the role of the formidable Voldemort. Previously embodied by actors like Ralph Fiennes and Hero Fiennes Tiffin, portraying such an iconic villain would undeniably be a significant challenge. Murphy’s involvement could mean revisiting younger versions of Voldemort, yet his performance would mark a new chapter in the character’s legacy.

Though HBO has neither confirmed nor denied these casting speculations, Murphy’s potential selection is further solidified by the support of Ralph Fiennes, who has praised him as a brilliant actor. This endorsement raises intriguing possibilities for the show’s direction.

6 Rachel Weisz

Minerva McGonagall

Rachel Weisz is another name generating buzz for the role of the esteemed Professor McGonagall. A fan favorite at Hogwarts, she served as head of Gryffindor House and Transfiguration professor before ascending to headmistress after Dumbledore’s passing. Weisz, known for her powerful portrayals, could bring a depth to McGonagall that resonates well with audiences.

Despite uncertainties surrounding her casting, industry rumors persist that discuss Weisz in connection with the role. Her fans will eagerly await confirmation or details, as the casting process unfolds.

5 Sharon Horgan

Minerva McGonagall

Another potential contender for Professor McGonagall is Sharon Horgan. With her successful track record as a showrunner and actress, especially in acclaimed series like Bad Sisters, her comedic timing would be distinctively valuable for the character, who balances strength and care.

Horgan faces the daunting task of living up to Dame Maggie Smith’s legacy, the previous portrayor of McGonagall. Nevertheless, her unique artistic vision and skills could reinvigorate the character for a new generation of fans.

4 Brett Goldstein

Rubeus Hagrid

Rumors suggest that Brett Goldstein could step into the beloved role of Rubeus Hagrid, previously portrayed with warmth and humor by Robbie Coltrane. Goldstein’s renowned comedic background, particularly in productions like Ted Lasso, positions him as a candidate capable of blending comedic elements with Hagrid’s more serious moments.

His theatrical experience—though not widely recognized—equips him well for portraying Hagrid, who often served as a source of levity in darker narrative arcs. As the casting process continues, Goldstein emerges as a strong candidate for this pivotal role.

3 Especially Essiedu

Severus Snape

Paapa Essiedu is also emerging as a frontrunner for the influential role of Severus Snape. Known for his compelling performance in I May Destroy You, Essiedu showcased exceptional depth and emotional nuance, critical to embodying Snape’s complex persona.

As production for the Harry Potter series gears up for a summer 2025 start, sources suggest that negotiations regarding Essiedu’s potential casting are underway. However, final confirmation remains pending as HBO continues its pre-production processes.

2 Mark Rylance

Dumbledore

Mark Rylance is among the early favorites to portray Albus Dumbledore in the upcoming series. Known for his versatility, Rylance has the ability to embody both benevolent and sinister roles, adding depth to Dumbledore’s complex character.

His strong background with the Royal Shakespeare Company and extensive filmography promise a captivating representation of the Hogwarts Headmaster, following in the footsteps of Richard Harris and Michael Gambon, who also brought theatrical finesse to the character.

1 Mark Strong

Dumbledore

Additionally, Mark Strong is rumored to be in contention for the role of Dumbledore, presenting another impressive option. While both Strong and Rylance are strong contenders for this iconic character, Strong’s extensive acting background, which includes acclaimed films like Tinker Tailor Soldier Spy, positions him as a compelling choice.

As HBO progresses through their casting deliberations, the network has indicated that they will confirm details as they finalize agreements, leaving fans eagerly anticipating the final decisions regarding who will embody these legendary characters.
