Earlier, while speaking about the much-anticipated Avengers 3 trailer, actor Paul Bettany – who plays Vision in the Marvel Cinematic Universe (MCU) – had teased that the Infinity War preview would be worth the wait.

Bettany revealed at the time that he had watched the "badass" and "amazing" trailer on co-director Joe Russo's phone. When he was asked about its release date, he teased, "It'll be out, everyone will love it."

Sebastian Stan, who plays Winter Soldier/Bucky in the Captain America movies, also had high praise for the film. "Almost every scene is epic," he said.

The movie will feature the Avengers – torn apart after the events of Captain America: Civil War – joining forces with the Guardians Of The Galaxy to battle villain Thanos, who is trying to collect the Infinity Stones for a gauntlet that will allow him to inflict his will on all "reality".

Avengers 3 is scheduled to release on 27 April in the UK and on 4 May in the US.

As for Avengers 4, Marvel boss Kevin Feige had earlier hinted in an interview with Vanity Fair that the Avengers franchise will end after the final Infinity War movie. The Avengers 4 film, which is due in May 2019, will "bring things you've never seen in superhero films: a finale", according to Feige.

He added, "There will be two distinct periods. Everything before 'Avengers 4' and everything after. I know it will not be in ways people are expecting."
