Avengers Endgame NEW TRAILER: It's THANOS! Mad Titan returns as heroes plot revenge

The new minute-long “Special Look”, available to watch below, arrives as tickets finally go on sale. We see the heroes reuniting and coming together as they prepare to face Thanos for one final showdown. Note the new emphasis on Iron Man and Captain America’s reunion, an emotional embrace with Pepper Potts, and a little more focus on Nebula. Watch above.

This could be the last trailer, aside from tiny TV spots, that we get before the film is out.

With just weeks to go ahead of its April 25 release date, the hype machine is starting to pick up serious momentum – not that it really needed much more in the first place.

A fan event for London has been scheduled for next week with the directors and some of the film’s stars – the ballot for tickets is open now.

Chris Hemsworth and Paul Rudd are also confirmed for The Graham Norton Show next Friday, April 12.

Thanos can be heard growling in the new clip: “You could not live with your own failure.

“Where did that bring you? Back to me.”

The story of the film is being kept under wraps, particularly because it remains a total mystery how the many dead heroes from Avengers: Infinity War can be brought back.

Popular characters such as Spider-Man, King T’Challa, Scarlet Witch and Doctor Strange were turned to dust at the close of that blockbuster, when Thanos successfully collected all six of the Infinity Stones and was able to eradicate half of all living things in the universe.
