Joe and Anthony Russo, the sibling directorial team who helmed Captain America: The Winter Soldier, have been confirmed to direct both parts of Disney-Marvel's Avengers: Infinity War.  The news has been the worst kept secret in Hollywood and the Russo's have been known to be in talks for months.

AvengersAvengers: Age of Ultron will be Joss Whedon's final movie in the Avengers franchise

The Russo's will take over from Joss Whedon, who directed The Avengers and the upcoming Avengers: Age of Ultron, which opens on May 1. They now represent Marvel's most used directors, having been enlisted to make four movies for the studio. Whedon has only directed the two Avengers films while Jon Favreau took charge of two Iron Man movies. The Ohio-born brothers are among the most sought after directors on the planet and they're also attached to The Gray Man as well as a male-orientated Ghostbusters movie for Sony (probably with Channing Tatum in the lead).

The Russo's signed a three year first-look deal with Sony Pictures that begins in April, though it's unclear whether the studio will wait for the brothers to finish Civil War before moving ahead with their own projects.

Captain America: Civil War, the brothers' next film, will include Sony's new Spider-Man character as part of the deal signed on February 9 between Sony and Marvel.

There is a suggestion that Whedon's Avengers: Age of Ultron could become the highest grossing box-office movie of all time when it opens in May. Early indications suggest it will break the $1 billion barrier.
