Young fella Will Poulter cast as creepy clown in It remake

In 1986, Stephen King released a book called It about a thing which manifests as a clown and menaces a group of children who later return to battle it again as adults.

I didn't read the book at the time (being about 3 years old) but I did spy the TV miniseries which released in 1990 and - like many of my era - was scarred for life by Tim Curry's take on the clown-looking monster. I mean, look at this thing!
