A 42-year-old man failed to play Hermione Granger in the new TV adaptation of Harry Potter.

HBO’s reimagining of JK Rowling’s wizarding books has ignited the hopes of actors everywhere that they, too, could be catapulted to fame, just as the original childhood trio of Daniel Radcliffe, Emma Watson was and Rupert Grint.

Seeing a deluge of more than 30,000 applications for just a handful of roles, the producers of the new series were overwhelmed by the interest from actors.

Every day, a team of casting agents are tasked with sifting through 1,000 audition tapes in an effort to discover the next Harry Potter, Ron Weasley, or Hermione Granger.

However, given the large number of applications, there were some interesting expressions of interest in the roles, including that of Hermione, with the 42-year-old falling at the first hurdle.

Had he succeeded in his ambitious bid, the man could have appeared on screen alongside Sir Mark Rylance, Paapa Essideu and Cillian Murphy, all of whom would be part of an all-star cast.

Despite the rejection of 42-year-old Hermione’s hopeful, final decisions have yet to be made regarding the roles, according to series ghostwriter Francesca Gardiner.

Calling the casting challenge “daunting”, Gardiner said the production team aimed to closely follow the exact ages of the characters in JK Rowling’s original novels.

The adaptation is expected to closely follow JK Rowling’s original novels, with the author apparently also responsible for the final call regarding casting.

Filming on the new adaptation is due to begin in summer 2025 at Warner Bros Studios near Watford, Hertfordshire, with each novel set to be turned into its own series as part of a ten-year plan.

The original films, which were produced over a ten-year period between 2001 and 2011, boasted a who’s who of British royalty.

From Dame Maggie Smith, Alan Rickman and Michael Gambon to Robbie Coltrane and Miriam Margolyes, many expect the new TV series to possess a similarly moving appeal.

This sentiment was supported by comments from series director Mark Mylod, who previously worked on the gripping HBO series “Succession.”

“We are going to follow the films philosophy to find some of the best British talent and brilliant theater actors that we are lucky to have over the generations,” Mylod said.

Although no final casting decisions have been made, there have been numerous reports in US industry publications regarding the big names being approached by HBO.

Los Angeles-based Variety magazine reported that Sir Mark Rylance had been approached to take on the mammoth role of Hogwarts headmaster Dumbledore.

Meanwhile, the Hollywood Reporter wrote that Paapa Essideu has been earmarked as the next Severus Snape, with Irish Oscar winner Cillian Murphy in line to appear as the franchise’s antagonist, Voldemort.

Irish Oscar winner Cillian Murphy is reportedly set to play the role of franchise villain Voldemort.

However, as MailOnline revealed earlier this year, JK Rowling is expected to have the final say on all major casting decisions.

It’s not just the wizarding world cast that fans can expect to change, with some differences to Hogwarts Castle itself also on the cards.

HBO’s Mark Mylod said the first eight-hour series would explore the famous castle in great detail, showing its “depths and crevices” to viewers.

Wanting to reflect how Hogwarts would evolve over time, Mylod said: “Our approach is not to undermine what has been done before, but to evolve it.”

“We don’t want to touch the Great Hall built in 900 AD, but we will expand on other elements of Hogwarts to explore the idea that if it was a real college it would have evolved to include elements of the Georgian architecture, for example.
