International Casting News: Harry Potter Reveals Key Season 2 Roles as Heated Rivalry Adds Milla Jovovich
September 5, 2026
Two major television productions have expanded their casts with significant new additions. HBO’s Harry Potter adaptation has found its young Tom Riddle, Dobby and a new Ginny Weasley, while Canadian drama Heated Rivalry is bringing Milla Jovovich, Kevin Zegers and Paul Gross into its second season.
Here are the latest casting developments.
HBO’s Harry Potter Casts Tom Riddle, Dobby and a New Ginny Weasley
HBO has announced three important additions to Season 2 of its Harry Potter television adaptation, which will move the story into the events of Harry Potter and the Chamber of Secrets.
British actor Billy Barratt has been cast as Tom Riddle, the younger version of the character who eventually becomes Lord Voldemort. Barratt is known for projects including Bring Her Back and Apple TV+ series Invasion.
BAFTA-winning actor Lenny Rush will portray Dobby, the house-elf who becomes one of Harry Potter’s important allies. Meanwhile, Bonnie Hill has been selected as the new Ginny Weasley. Hill replaces Gracie Cochrane, who portrayed Ginny during the first season but departed before Season 2.
The three roles are especially significant because Chamber of Secrets substantially expands the stories of Ginny, Dobby and Tom Riddle.
Why It Matters for Casting
The casting of Billy Barratt as Tom Riddle is particularly notable because the character plays a central role in the mythology surrounding Voldemort.
At the same time, casting Lenny Rush as Dobby demonstrates how performance casting remains important even for characters that will rely heavily on visual effects.
Replacing Ginny between seasons also shows one of the challenges of building a long-running adaptation around young actors: producers must consider both the immediate performance and how performers can develop alongside their characters across multiple seasons.

Milla Jovovich, Kevin Zegers & Paul Gross Join Heated Rivalry Season 2
Heated Rivalry is expanding its Season 2 ensemble with three recognizable performers: Milla Jovovich, Kevin Zegers and Paul Gross.
Jovovich, internationally known for films including The Fifth Element and the Resident Evil franchise, will play Dr. Galina Molchalina, a psychologist who works with Ilya Rozanov.
Kevin Zegers has been cast as Brandon Wiebe, coach of the Ottawa Centaurs, while veteran Canadian actor Paul Gross will portray hockey commissioner Roger Crowell.
They join returning leads Hudson Williams and Connor Storrie, who play rival professional hockey players Shane Hollander and Ilya Rozanov.
The second season has been building a considerably larger ensemble. Other previously announced additions include Justice Smith, Charlie Gillespie, Emily Hampshire, Edvin Ryding, Robert Naylor, Sabrina Jalees and Priyanka.
Season 2 is expected in 2027, with the series airing on Crave in Canada and streaming on HBO Max in the United States.
Why It Matters for Casting
Adding Milla Jovovich represents an important shift in the scale of the show’s casting.
The series originally built much of its popularity around emerging performers, particularly its central leads. Bringing an internationally established film star into Season 2 can expand the production’s visibility beyond its existing audience.
Zegers and Gross also add experienced Canadian performers to a series that has become one of Canada’s increasingly visible international television exports.

What These Castings Show
These announcements highlight two different casting strategies.
Harry Potter is carefully selecting young performers for characters audiences already know extremely well, where expectations around appearance, personality and long-term character development are unusually high.
Heated Rivalry is doing the opposite: expanding an established ensemble by introducing more recognizable performers as the series grows internationally.
Both demonstrate that casting is not simply about choosing famous actors. It is about finding performers who support the next stage of a production’s story, audience and identity.
