Fans aren't happy about new actors playing the iconic characters in Harry Potter TV show

It looks like we're going back to Hogwarts, but on a much smaller screen.

While the announcement has sparked loads of joy amongst some wizards and witches around the world, some aren't happy about the idea.

But fans have flocked to social media to share their disappointment at the idea that a whole new batch of actors will have to be cast and they're worried it will erase the legacy established by the movie franchise.

The official Harry Potter Universe Twitter page wrote about the decision, saying: "This new Harry Potter TV series will replace all of our favorite actors from the films and, despite being a massive fan of everything Harry Potter, I will NOT support it."

They added: "Really bummed about this. The films only finished a decade ago, and now there’s going to be all new actors playing the characters. Can’t picture anyone other than Alan Rickman as Snape, Robbie Coltrane as Hagrid, Emma Watson as Hermione, and so on."

Another fan wrote: "There will NEVER be another Harry, Ron or Hermione that isn't played by Daniel Radcliffe, Rupert Grint and Emma Watson. A remake of Harry Potter is OFFENSIVE, an IMPECCABLE cinematographic work that has no NEED to be played. We don't want HBO!"

A third quipped: "If it’s not Emma, Daniel and Rupert I don’t want it. Also. I love Harry Potter so much. But why does HBO Max insist on remaking everything that was iconic in the past instead of developing more new and fresh content?"

Some have called on HBO to cast people who are completely unknown talents rather than established names to ensure the story of JK Rowling's work shines through.

Fans who are excited about the project are looking forward to seeing all the parts from the books that never made it into the film.

The seven-book TV show adaptation has been described as a 'decade-long' undertaking that will flesh out all the words written by Rowling.

There's no word yet on when we can expect to see the show drop on TVs around the world but you can bet your bottom dollar that it will be one of the biggest series ever.
