With one of the core themes of the source material being childhood fear, and the way we deal with it as adults, this first half to the two-film Stephen King adaptation will be heavily mining the younger aspect of the story.
If anything, we’re kind of excited to see how horrified the reactions of the child cast of the film will be.
Thinking back to the trailers and promotional material we’ve seen for IT, the approach that Bill Skarsgard has taken towards his character work for Pennywise has indeed paid off.
So the more scared we see these kids on screen, it’s hypothetically possible that the adult portrayals will be that much more powerful when we see the older versions of the cast face off against the eternal clown evil.
