Johnny Flynn in Emma.

I just heard that the great Johnny Flynn with be playing Mr. Malfoy in the new HBO TV series, which is sensational news for Harry Potter fans, which I want because Johnny is a brilliant actor. Irritatingly, he’s a brilliant musician as well, and a really lovely guy…and I can’t wait to see what he comes up with. Johnny, if you’re watching this, enjoy yourself.

A fantastic actor, a lovely man and, irritatingly, a rather brilliant musician too. Couldn’t have handed the snake-topped baton on to anyone better. Just please don’t make him sing…

Our Take On Jason Isaacs' Reaction To Johnny Flynn’s Lucius Malfoy Casting

Jason Isaacs Is Intrigued, And So Am I

Isaacs has taken the news very well, with his messages both positive and lighthearted. In the video, he jokingly offers Flynn one piece of advice as the former Lucius Malfoy, warning the musician about Dobby, who betrays his character and turns to help Harry Potter instead. He also teasingly “warned” HBO not to make Flynn sing in the upcoming reboot. It seems thatFlynn’s casting has sparked a special interestin theWhite Lotusactor, who is now curious to see the new take.

As a longtimeHarry Potterfan, Ican certainly picture Johnny Flynn, who is very versatile as an actor, as Lucius. Though information has been scarce so far, I’m very intrigued to hear his take on the character and see what he does with the role. It is especially exciting because Lucius is not introduced until the second book and the second movie, but this casting indicates that he will appear in season 1, with the show establishing his important story sooner.
