We all thought that Captain America: Civil War was inconceivably huge, with its two opposing armies of superheroes, but the more we read about Avengers: Infinity War, the clearer it is that we ain't seen nothin' yet.
The Marvel Cinematic Universe has been building up to the cosmic bust up for years—and it will stretch over two films, with triple the cast of Cap's latest outing.
Winter Soldier and Civil War directors Anthony and Joe Russo are back to tackle Marvel's monster, which will reunite them with writers Christopher Markus and Stephen McFeely. Guardians of the Galaxy director James Gunn is serving as executive producer, and Spider-Man: Homecoming's Jon Watts is involved too.
But what can we expect when the mad titan Thanos comes out swinging for the double movie? Here's everything you need to know to prepare for the all-out Avengers war:
Avengers: Infinity War trailer: it's a super smash
The first trailer for Avengers: Infinity War exploded at the end of Disney's D23 Expo to a standing ovation from the crowd. Sadly right now Disney hasn't released the footage . Unfortunately, it's STILL not ready for wider consumption, apparently.
Digital Spy was lucky enough to catch it though, and this is what we saw:
As it begins, Thor is literally floating through space when he crashes into the Milano (Star Lord's spacecraft from Guardians of the Galaxy) and is brought on board by the Guardians.
He's unconscious and suddenly pops up as they examine him, to shout: "Who the hell are you?" before Thor leads the Guardians to meet the rest of the Avengers.
Other highlights are when we see Peter Parker get the Spidey Sense on his school bus for the first time, sensing Thanos is coming. We later see Spidey in action in what appears to be the Iron Spider suit (super exciting).
There's a very brief snippet of Scarlet Witch blowing up a bunch of cars. There's no context for this—could she have gone rogue?
Tom Hiddleston is back as Loki (yey!), briefly shown holding the Tesseract in the middle of destruction.
There's a massive fight between the Avengers and the Guardians with Thanos. Thanos literally knocks the armor off Iron Man. Tony also brings back the Hulkbuster armour.
"Fun isn't something one really considers when restoring balance to the universe. But this put a smile on my face," Thanos says as he wallops EVERYONE.
Oh and Steve Rogers has a beard. A BEARD we tell you!
Avengers: Infinity War release date – One film or two?
First billed as a two-part movie, with Avengers: Infinity War – Part 1 being followed a year later by Avengers: Infinity War – Part 2, the latest seems to be that Marvel is drawing a more rigid line between them.
The first movie will be simply Avengers: Infinity War, and will follow the familiar pattern of releasing first in the UK, on April 27, 2018, then following in the US on May 4, 2018.
The second film is currently known only as 'Untitled Avengers'. That's coming to the UK on April 26, 2019, and the US on May 3, 2019. It started shooting in summer 2017.
The Russos had already said that the previous titles were "misleading" and that the two films were going to be "very, very different." The question remains as to just how related or separated they will turn out to be. The eventual announcement of the second title should shed some more light on this particular mystery, though it looks like we'll be waiting for some time for that.
We got an early peek at what appears to be Josh Brolin in a mo-cap suit sitting during rehearsals, and now shooting is officially underway on the film. Keep an eye on the Russo brothers' Facebook page for more behind-the-scenes images as filming continues.
Sean Gunn (Guardians of the Galaxy actor and brother of director James Gunn) gave us what might be a first look at Infinity War's branding.
Avengers: Infinity War cast – Thanos is sitting pretty
Marvel has kept quiet on the complete cast of Infinity War. But with an estimated 67 characters showing up over the course of the movie and its follow-up, we can assume that plenty of familiar Avengers faces will be in the mix.
As the main villain of the piece, there is no doubt that Josh Brolin's Thanos will be making an appearance—and he may be more than pure CGI this time—and will be subverting Marvel's villain problem by serving as the "main character" in the film.
Chris Hemsworth's Thor, Chris Pratt's Star-Lord, and Elizabeth Olsen's Scarlet Witch/Wanda have also been confirmed by the directors, and the Guardians of the Galaxy will be joining them, including Star-Lord (Chris Pratt), Gamora (Zoe Saldana), Drax (Dave Bautista), Rocket (Bradley Cooper/Sean Gunn), Groot (Vin Diesel), and Mantis (Pom Klementieff). If they look a bit long in the tooth, it's because four years have passed since Guardians of the Galaxy Vol 2.
Jeremy Renner has revealed that Hawkeye will return to shoot another day, and Robert Downey Jr is back as Iron Man. It looks like they'll be thawing Sebastian Stan's Winter Soldier out for the movie, too.

Seems pretty likely Doctor Strange will be joining the movie too. Benedict Cumberbatch hinted as much in an interview where he admitted that there is a "logistical challenge" of lining up his schedule with the other Marvel stars…but said the team are making it work.
