Thor: Ragnarok saw the reunion of some of the mightiest superheroes, and following its success, expectations surrounding upcoming Marvel blockbuster, Avengers Infinity War, has been soaring.

While directors Joe and Anthony Russo remain tight-lipped, Paul Bettany is giving a little teaser on what to expect in the first trailer.

The actor – who initially voiced Jarvis and now plays The Vision, the all-powerful android – revealed he has watched a cut of the trailer on director Joe's phone and, if his words are any indication, the first look is going to be "badass" and "amazing".

"It'll be out, everyone will love it," Bettany said, teasing fans about the first trailer during a recent panel at Rhode Island Comic Con, according to reports.

As if the anticipation wasn't at its peak already, Winter Soldier star Sebastian Stan added his own bit, highlighting the trend shown by Marvel movies of building towards an epic finale.

Unlike previous instalments though, Stan explained that in Avengers: Infinity War "almost every scene is epic" right till the end.

Following the events of 2016's Captain America: Civil War, that saw the team of superheroes engage in a war among themselves over newly-introduced government laws, Infinity War is all set to reunite the Avengers to fight a greater threat – Thanos.

A trailer for the first look of the Avengers film, which is set for a 2018 release, is yet to be revealed. And the Russo Brothers are not making the wait any easier. They recently shared some information in the form of a brief clip via Instagram, teasing alongside, "Regarding your demands for the release of the Infinity War trailer..."

But the video happened to be just an old wine commercial with a cheeky tagline driving home the message for Marvel fans, "We will sell no wine before its time."

Hopefully, the first trailer will be out by the end of this year, if the numerous fan theories posted on Reddit are anything to go by.

In the meantime, though, Marvel Studios boss Kevin Feige has dished on the experience of filming Infinity War. "I guess what has surprised me is how emotional it all is," Feige told Collider.

"Every day, every dailies, every time an actor that has never interacted with a character comes in contact with a character they've never interacted with, it's amazing."

Feige was also all praises for the cast and crew involved with the superhero movies, and for "Joe and Anthony [Russo] handling it, two movies at the same time, in an unprecedented fashion".

Avengers: Infinity War releases in 2018 on 27 April in the UK and on 4 May in the US.
