Josh Brolin stars as Thanos in the upcoming superhero showdown Avengers: Infinity War and he's promised that the full story of the film is "incredible".

Chatting exclusively to Digital Spy to promote the DVD and Blu-ray release of the Coen brothers' '50s Hollywood-set comedy Hail, Caesar!, the actor was understandably guarded about the two-part Marvel blockbuster.

"I literally can't say one word about it, but it's an incredible story," he told DS. "There's no script yet. But I do know the story inside and out and it's an amazing story.

"I sat at a table and listened to the story and was completely and utterly blown away. I was told it by all the people involved. It was a large table, I'll put it that way!"

Thanos has made cameo appearances in The Avengers, Guardians of the Galaxy and Avengers: Age of Ultron, but Infinity War is where the Marvel Cinematic Universe's big bad is likely to come into his own.

Avengers: Infinity War - Part 1 is scheduled to release on May 4, 2018, while Part 2 is due out on May 3, 2019.

Before then, Brolin will star in Granite Mountain opposite Miles Teller, which is currently filming, and Soldado, the sequel to Sicario.

There's also Suburbicon, directed by his recent co-star George Clooney and based on a script by the Coens which will feel like a spiritual cousin to Hail, Caesar!.

"It's another one of those things where it's like, 'Hey will you think about doing this for me?' and I said yes immediately," says Brolin.

"I read it and I thought it was extremely funny. I have a thing with the [Coens].

"I enjoy them very much and it makes me happy working on their movies and I continue to do so even though nobody's really being paid anything and it seems like a waste.

"It's not a waste! It's so satisfying on every level and you hope that other people feel the same way."
