Coming in out of nowhere, a new trailer for 'Avengers: Endgame' has landed online and shows some new footage from the eagerly-awaited comic-book blockbuster.

Following a similar theme to the previous trailer, you've got the surviving Avengers looking mean and moody, talking about how they can't get over what Thanos did, and - by all accounts - vowing revenge on him, because, you know, it's in their name.

The trailer does feature two big reveals - one of them being the Avengers' spiffy new space-suits, which look like they're pulled right from the cartoon series 'Avengers: Earth's Mightiest Heroes'. The other, of course, is Captain Marvel herself joining the team and being introduced to Thor.

Other than that, about 40% of the trailer is made up of clips from the first 'Iron Man', 'Thor' and 'Captain America' movie, clearly drawing on the Marvel Cinematic Universe's decade-long legacy. Given how 'Avengers: Endgame' is going to be the final chapter for any one of these characters, there's clearly some significance in having these moments in the trailer.

As well as this, the new poster for 'Avengers: Endgame' also debuted online at the same time, and features the line-up for the movie including Captain Marvel in pride of place just above Captain America and right next to General Okoye.

Right, that's enough filler. Watch the trailer already.
