We hope you're sitting comfortably.
Now that the first teasers have dropped and brought the evil Pennywise and the grown-up Losers' Club back into our lives, there's one pressing question we need answered: how long is It Chapter Two going to be?
Well, thankfully, the film's director Andy Muschietti has shed some light on that front as he reflected on putting the film together, and it looks like it's time to start preparing for an epic stint in the cinema.
The film is currently coming in at a whopping 2 hours and 45 minutes – but don't worry, the director also shared that he's had no complaints about the length of the film from those who've already seen it.
"A movie is very different when you're writing the script and you're building a story compared to what the final product is," Muschietti told Digital Spy and other press.
"At the beginning, when you're writing and building the beats of the story, everything that you put in there seems very essential to the story. However, when you have the movie finally edited and it's 4 hours long, you realise that some of the events and some of the beats can be easily lifted but the essence of the story remains intact.
"You cannot deliver a 4-hour movie because people will start to feel uncomfortable – no matter what they see – but we ended up having a movie that is 2 hours and 45 minutes, and the pacing is very good.
"Nobody who's seen the movie has had any complaint."
Of course, the runtime isn't quite as long as Avengers: Endgame (and that's certainly not done too badly at the box office) but it looks like we'll at least get a chance to see some of the moments that ended up on the cutting room floor in this film, with producer Barbara Muschietti promising a director's cut.
"We will put out a director's cut because this time it definitely merits it,"
"We have some amazing scenes that didn't make it into the movie. You have to make choices sometimes and some things cannot be in this theatrical release but are definitely worthy of people seeing them at a later date."
And just in case you were worried that It Chapter Two had cut out all the scary bits, Andy also stressed that there haven't been any issues over any scenes being too horrific to include in the final film.
"Oh, no," he replied. "Everything that is too scary is in the movie."
Phew. That's a relief. (And also an absolutely terrifying thought.)
