- Tilda Swinton is the 1/2 favourite to play Lord Voldemort in HBO’s Harry Potter reboot

- Swinton leads a list of contenders including Gwendoline Christie, Matthew Macfadyen and Tom Hiddleston
Tilda Swinton now favourite to play Lord Voldemort
With bookmakers continuing to offer novelty markets around big-budget reboots a surprising twist in the casting race for the HBO Harry Potter series has propelled Tilda Swinton into pole position to play Lord Voldemort.
As betting sites react to new reports that the role may go to a woman, Swinton’s odds have shortened significantly and fans are buzzing about what a female Dark Lord could look like on screen.
According to respected entertainment insider Daniel Richtman, auditions are now open to both male and female actors, raising the very real possibility of a gender-swapped Voldemort for the first time in franchise history.
The much-anticipated Harry Potter TV series, currently in production and set for a 2027 premiere, has drawn headlines for its intent to stay faithful to the original books but now it's the casting of its central villain that’s making waves.
Who Will Play Lord Voldemort in HBO’s Harry Potter?
| To Play Lord Voldemort in HBO’s Harry Potter | Odds | Implied Probability |
|---|---|---|
| Tilda Swinton | 1/2 | 66.7% |
| Gwendoline Christie | 2/1 | 33.3% |
| Matthew Macfadyen | 3/1 | 25.0% |
| Paul Bettany | 3/1 | 25.0% |
| Tom Hiddleston | 6/1 | 14.3% |
Swinton's move to 1/2 odds reflects both growing whispers from inside HBO and her unmatched ability to play mysterious, cold, and androgynous characters.
Gwendoline Christie, best known as Brienne of Tarth in Game of Thrones, sits second in the market at 2/1
Why a Female Voldemort Makes Sense
HBO appears unafraid to challenge traditional portrayals, especially if the actor best captures the essence of the character, regardless of gender.
Paapa Essiedu's portrayal of Professor Snape has changed the expectations around casting for the show and created headlines throughout the early process.
A gender-swapped Voldemort wouldn’t just be a headline-grabber but it would give HBO the chance to deliver a fresh psychological perspective on Tom Riddle’s descent into darkness.
