Ron Weasley star Grint told GMB in January: “I can’t really think of a reason not to. I love that character, I love that world. It’s a huge part of my life. I would [come back]. If the others did, I think, yeah!”
On top of him, Christopher Columbus who directed the first two Harry Potter movies would love to helm a Cursed Child movie.
Also referencing the Star Wars sequel trilogy, he told The Hollywood Reporter: “A version of Cursed Child with Dan, Rupert, and Emma at the right age, it’s cinematic bliss. If you’re a film nerd or cinephile, it’s kind of like what J.J. [Abrams] did with Star Wars. Star Wars really started to be great again when J.J. made the film and we had all the original cast back. There’s no question if you’re a Star Wars fan, you were moved just seeing them on screen. Seeing Harrison Ford as Han Solo again, and Chewy. It was very moving.”
