Leo Earley, a seven-year-old from Co Leitrim, has been cast as Irish wizard Seamus Finnigan in HBO's upcoming "Harry Potter" series.

Earley's casting was announced by HBO earlier this week.

In the original "Harry Potter" book series, Seamus Finnigan, a Gryffindor pupil, arrived at Hogwarts from Ireland in the same year as Harry, Ron, and Hermione.

Best friends with Dean Thomas, the young wizard Seamus wasn't always on Harry's side, especially when rumours began to form about whether he was always telling the truth, but despite this, he stepped up where it counted and fought bravely when Lord Voldemort made his return.

In the film series "Harry Potter," Seamus Finnigan was played by Devon Murray, an actor from Co Kildare.

Earley had a taste of stardom on RTE's "The Late Late Toy Show" last year when he delivered a humorous monologue as a Seanchaí:

His "Late Late Toy Show" feature came a few months after the Leitrim lad won the Under 12 Storytellling Competition at the All-Ireland Fleadh Cheoil 2024:

Filming of HBO's "Harry Potter" series will take place this summer in the UK.

HBO says that its new "Harry Potter" series, which is set to be filmed in the UK this summer,  "will be a faithful adaptation of the beloved 'Harry Potter' books by author and executive producer J.K. Rowling.

"Each season will bring Harry Potter to new and existing audiences, streaming exclusively on HBO Max where it’s available, including in upcoming launch markets Germany, Italy and the UK.

"The original classic films will remain available to watch around the world."

In previous casting announcements, Dominic McLaughlin was confirmed to be playing the titular Harry Potter, Arabella Stanton is Hermione Granger, and Ron Weasley will be played by Alastair Stout.

John Lithgow has been cast as Albus Dumbledore, Janet McTeer as Minerva McGonagall, Paapa Essiedu as Severus Snape, Nick Frost as Rubeus Hagrid, Luke Thallon as Quirinus Quirrell, and Paul Whitehouse as Argus Filch.

Alongside this week's announcement that Earley will be playing Seamus Finnigan, HBO revealed that Molly Weasley will be played by BAFTA winner Katherine Parkinson, while Draco and Lucius Malfoy will be played by Lox Pratt and Johnny Flynn respectively.

Also joining the cast of Hogwarts students are Alessia Leoni as Parvati Patil and Sienna Moosah as Parvati’s best friend, Lavender Brown.

Additionally, Bel Powley has been cast as Petunia Dursley, with BAFTA winner Daniel Rigby joining her as Vernon Dursley.

Meanwhile, double Olivier and Tony Award-winning performer Bertie Carvel will be portraying Cornelius Fudge.
