Joe and Anthony Russo have been confirmed as directors of the next two 'Avengers' movies.

The brothers - who first worked with Marvel on 2014's 'Captain America: The Winter Soldier' - were rumoured last month to have signed a deal with Marvel to direct 'Avengers: Infinity War' parts one and two, but now Marvel has officially confirmed that they will be taking over from Joss Whedon.

Both 'Avengers: Infinity War' films are expected to be shot back-to-back next year, after the Russo brothers have completed their work on 'Captain America: Civil War', the film they're currently preparing to shoot.

However, IGN News claims that they might not both still include Robert Downey Jr., Chris Hemsworth and Chris Evans, due to the amount of contractual movies each has left with Marvel.

Joss had already confirmed his intention to walk away from the 'Avengers' at the conclusion of 'The Avengers: Age of Ultron'.

He explained: ''I couldn't imagine [directing an 'Avengers' film] again.

''It's enormously hard, and it'd be, by then, a good five years since I created anything that was completely my own.

''So it's very doubtful that I would take on the two-part Infinity War movie that would eat up the next four years of my life.''

'Avengers: Infinity War Part 1' is expected to be released on May 4, 2018, with the second instalment set for May 3, 2019.
