You've set up camp outside your local cinema armed with a few blankets, some clean undies and provisional snacks. You've been participating in breathing exercises to try and keep your heart rate as normal as possible. You've even considered doing extra history revision to make sure you understand what's actually going on.
But now the wait is over. The first trailer for Christopher Nolan's Dunkirk, also commonly known as The Film That Harry Styles Is In, has arrived on the internet - and it's every bit as intense as you thought it would be.
So we're just gonna go ahead and say it, because we can't bear to disappoint you. There's not much Harry in here - in fact, he doesn't actually pop up in it at all, which is a bit of a blow.
But it's still TOTALLY worth a watch, as the trailer gives a really good insight into the kind of intense, dark, gritty and probably quite hard-to-watch movie that Harry's gonna make his debut in. He ain't that kid in the Jack Wills tees and purple trainers anymore, you guys.
ALRIGHT WE'LL SHUT UP NOW. Get watching and let us know what you think with a tweet to @Sugarscape.
