Since the confirmation of James Spader as the voice of Ultron in Avengers: Age of Ultron we’ve been waiting patiently for casting news for the newest Marvel super heroes, the twin siblings Scarlet Witch and Quicksilver.

Latino Review reports that our wait is over. Elizabeth Olsen (Silent House) will be playing Scarlet Witch, and her brother Quicksilver will be played by Aaron Taylor-Johnson, who is no stranger to fighting crime behind the mask of a superhero in his past works of Kick Ass and Kick Ass 2.

Avengers: Age of Ultron, starring Robert Downey Jr., Scarlett Johansson, Chris Evans, Chris Hemsworth, Mark Ruffalo, Samuel L. Jackson, Jeremy Renner, and James Spader, drops in to theaters in the summer of 2015.
