As per Variety, the title role in the upcoming remake of It has finally been cast:
That's Will Poulter, a 22-year-old British actor who has been doing VERY strong work for nearly a decade in movies ranging from Son of Rambow to We're the Millers to Voyage of the Dawn Treader to (I assume) the upcoming The Revenant, in which he is the fourth lead behind people like Tom Hardy and Leonardo DiCaprio.
Word is that Poulter's audition blew away Cary Fukunaga (who will be directing It), and if Fukunaga -- whose recent run on True Detective indicates a talent for directing actors that is not merely considerable but superior -- is sold on him, then so am I.
I have not looked around the Internet for reactions to Poulter's casting, but my knee-jerk suspicion is that there will be lots of people who are upset along the lines of "HOW CAN THEY TOP TIM CURRY WHARRRRRRRRRRGARBLE" and who don't go any farther in their thinking than that. I say this based purely on knowing how the Internet works; who knows, maybe this will be the moment things change.
But probably not, and in that case, I'd have to say that while Curry is certainly iconic in the role, he's by no means irreplaceable. Here ya go, a list of half a dozen actors who could do it as well or better, right off the top of my head:
You may or may not dislike some or all of those choices, of course; there's no accounting for personal tastes. But folks, in a world where it has been possible to recast James Bond successfully not just once but numerous times, you will never be able to sell me on the idea that Pennywise can't be successfully recast once. If you've got that mindset, good on ya; but you've got a very different one than I have, no doubt about it.
In any case, we'll see next year how this all works out. Let's hope it's great!
