Harry Potter TV Series Odds: Who Will Play Voldemort, Dumbledore And Hagrid?

HBO recently confirmed plans for a new Harry Potter TV series, and a casting call is under way to find three new actors to take on the roles of Harry, Hermione and Ron. 

The stars must be between the ages of nine and 11 in April 2025 and be residents of the UK or Ireland, and they are likely to be unknown actors. 

However, there has been lots of speculation on UK betting sites about who might appear as the likes of Voldemort, Dumbledore and Hagrid in the new series.

From Peaky To Potter 

Daniel Radcliffe, Emma Watson and Rupert Grint shot to fame as Harry, Hermione and Ron respectively in the eight movies - which were based on J.K. Rowling's best-selling book series - and the franchise has spawned several spin-offs, including the Fantastic Beasts series.

In the films, Harry's arch-enemy Voldemort was superbly portrayed by Ralph Fiennes, but Cillian Murphy has emerged as the 10/11 favourite on specials betting sites to land the role in the new TV series. 

The Peaky Blinders actor played no-nonsense gangster Tommy Shelby in the BBC series and will reprise his role in a forthcoming film.

A message on the X account of The Daily Harry Potter - which has more than 290,000 followers - recently read: "Rumours are growing that Cillian Murphy could be playing Lord Voldemort in Max's new Harry Potter series".

Harry Potter TV Series: Who Will Play Voldemort Odds:

Murphy could no doubt turn his hand to most parts, including Voldemort. But if HBO are looking to cast a star closer to home then Rhys Ifans could be a candidate with odds of 6/5 on specials betting sites. 

Ifans is a favourite of HBO thanks to his House of Dragon role as complex character Otto Hightower in the TV network's Game of Thrones spin-off, and he also appeared in the Harry Potter movies as Luna Lovegood's (Evanna Lynch) father, Xenophillius Lovegood. 

Ifans' House of Dragon co-star Matt Smith (5/2) could also be in the conversation to portray Voldemort, given how well he has played evil Daemon Targaryen in the fantasy series, but it wouldn't be a huge surprise if Fiennes (3/1) was offered the part again.

Oldman Odds-On For Dumbledore

Slow Horses star Gary Oldman portrayed Sirius Black in the Harry Potter film franchise, but he recently admitted nobody has "approached" him about reprising the part in the HBO series. 

While Oldman wanted Black to have a bigger role in the movie series, he is expecting a "whole new cast of people" in the new TV show - but he hasn't ruled out portraying Albus Dumbledore. He told IndieWire: "Maybe in a few years, I could do Dumbledore."

Following his comments, Oldman has emerged as the 8/13 favourite on betting apps to portray the Hogwarts headmaster. 

Others who could be in with a chance include Evens shot Jim Broadbent, who played Horace Slughorn in the eight Harry Potter movies.

Jude Law is someone who already has experience of portraying Dumbledore, after playing the character in 2018's Fantastic Beasts: The Crimes of Grindelwald and follow-up Fantastic Beasts: The Secrets of Dumbledore, in 2022. 

But Rupert Everett, who is 3/1 to be cast as the wizard, has already put his sorting hat in the ring for the role. 

When asked on ITV show This Morning whether he would be up for portraying Dumbledore, he said: "That’s my other dream! But that’s an uphill struggle too. Maybe, who knows?"

A lovely full circle piece of casting would see Jared Harris take on the coveted part, which was portrayed by his late father Richard Harris in the first two films, before Michael Gambon took over after Richard's death.

However, Jared (4/1) has appeared to rule out a potential appearance in the new TV series, which will have three very successful writers working on it. 

Speaking to The Independent, he said: "No, thank you. Also, I mean, why do it? 

"I don’t understand. The films were fantastic - leave them alone."

Big Shoes To Fill 

One of the many reasons for the movie series' success was Rubeus Hagrid. It's hard to imagine anyone other than the brilliant Robbie Coltrane portraying the friendly giant character, but Robbie sadly passed away in 2022, aged 72. 

Whoever lands the part of Hagrid in the HBO series will have, quite literally, big shoes to fill, and Nick Frost is the early 4/5 favourite to secure the role. 

Frost is no stranger to putting on a "country" accent, as he did in 2007 movie Hot Fuzz, which would lend himself well to portraying Hagrid, and the star has also been known to pull off a bushy beard like the character.

As well as appearing alongside Harry Potter stars Broadbent and David Bradley in Hot Fuzz, Frost also starred opposite Rory McCann, who played Lurch. 

At 6ft 6in, McCann - who is best known for playing The Hound in HBO's Game of Thrones - wouldn't need too much of a boost to be cast as Hagrid, and he is 7/4 to land the role. 

Ciaran Hinds (5/6) is another actor who could be in the running, and he has a Harry Potter connection. 

He played Dumbledore's brother Aberforth in Harry Potter and the Deathly Hallows - Part 2, but he is just 5/6 to take on the role of Hagrid in the TV series.
