Although it pretty much came out of the blue, the 'Ghostbusters' reboot / threequel / who knows has been building slowly for quite some time.

Earlier this year, Paul Rudd was officially confirmed as starring in the movie, along with 'Stranger Things' alum Finn Wolfhard, a good chunk of the original cast, and 'Fargo' Season 3 star Carrie Coon.

However, a major article by Vanity Fair has shed a lot of the secrets of the movie, including confirmation that a trailer for 'Ghostbusters: Afterlife' is coming tomorrow, Monday, December 9th.

So, on with the info-dump.

As was teased in that, well, teaser, the movie kicks off in a spooky farmhouse that belongs to Carrie Coon's unknown father, who we're definitely thinking is Dr. Egon Spengler. She and her two children, Finn Wolfhard and 'I, Tonya' star Mckenna Grace, move out to the farmhouse and - sure enough - find the old Ecto-1 and a bunch of 'Ghostbusters'-related paraphernalia.

The movie is set during our time, and refers to the events of the original 'Ghostbusters' - that's the giant Stay Puft attack in Manhattan, all the stuff with Gozer the Gozerian and the Keymaster - as "the Manhattan Crossip of 1984", which just so happened to be witnessed by Paul Rudd's character, a summer school teacher called Mr. Grooberson.

He, it turns out, is absolutely obsessed with the event and one of the promotional images shows him holding one of the ghost-traps. As well as this, the VF article confirms that "(most) of the original cast have committed to returning as their classic characters, although it’s not clear in what capacity they’ll appear." Sadly, however, it's not yet known if Rick Moranis will be returning as Louis Tully - but good news, Annie Potts is back as Janine.

All of it sounds pretty promising, even if it is taking the tried-and-tested structure for legacy sequels laid down by 'The Force Awakens' or 'Creed'.

For now, we'll just have to wait around for the trailer tomorrow. In the meantime, enjoy the best one-liner of Bill Murray's career from 1984's 'Ghostbusters'.
