Marvel officially confirms Aaron Taylor-Johnson and Elizabeth Olsen for The Avengers: Age of Ultron

Marvel Studios finally officially confirmed on Monday that Aaron Taylor-Johnson and Elizabeth Olsen would play the brother-sister superhero duo of Quicksilver and Scarlet Witch, respectively, in The Avengers: Age of Ultron.

The announcement hardly came as a surprise to anyone who had been following the casting news for the movie, as Taylor-Johnson and Olsen had spoken repeatedly about the parts and their names had been connected the roles for months. All that was left was the official announcement, which Marvel finally gave on Monday.

Quicksilver will also appear in the upcoming superhero blockbuster X-Men: Days of Future Past but will be played by Evan Peters (American Horror Story). Fox owns the rights to the X-Men franchise, so Marvel Studios cannot make reference to the fact that Quicksilver and Scarlet Witch are mutants, nor can Marvel mention that Magneto is their father.

Here's the official release from Marvel Studios via ComicBookMovie.com:

"Aaron Taylor-Johnson and Elizabeth Olsen have officially joined the Avengers family as the brother-sister duo of Quicksilver and Scarlet Witch in Marvel's "Avengers: Age of Ultron," the highly-anticipated sequel to 2012's smash-hit "Marvel's The Avengers"! "Avengers: Age of Ultron" arrives in theaters May 1, 2015. 

Taylor-Johnson broke out with his roles as Dave Lizewski in the "Kick-Ass" franchise and with his portrayal of a young John Lennon in "Nowhere Boy," for which he won an Empire Award for Best Newcomer. Since then, Taylor Johnson has starred in 2012's critically-acclaimed "Anna Karenina" and director Oliver Stone's "Savages." 

Since making her big screen debut in 2011 with "Silent House" and "Martha Marcy May Marlene," for which the actress garnered a number of awards and nominations, Olsen has gone on to star alongside the likes of Robert DeNiro and Sigourney Weaver in "Red Lights," Josh Brolin and Samuel L. Jackson in director Spike Lee's "Oldboy." 

Taylor-Johnson and Olsen will share the screen as leads in the highly anticipated "Godzilla" remake scheduled for a May 2014 release. 

"Avengers: Age of Ultron" will bring the Marvel Universe's biggest heroes together again to face one of their biggest villains, with "Marvel's The Avengers" director Joss Whedon returning to write and direct the sequel. 

"Marvel's The Avengers" was released in 2012 and went on to earn $1.5 billion worldwide, making it the third-largest grossing movie of all time.
