Joss Whedon is looking to bring two more names to his highly anticipated follow-up to the already packed list of super heroes that make up The Avengers. For the sequel, "Age of Ultron" Quicksilver and The Scarlet Witch will be added to the mix and it appears Whedon has found his Scarlet Witch.

Rumors have been circulating that Elizabeth Olsen, sister of Mary-Kate and Ashley Olsen, is being eyed by Whedon for the role. While she isn't necessarily a high-profile choice for the role, she has made a name for herself recently by taking on challenging starring roles in independent films like "Liberal Arts" and "Martha Marcy May Marlene." In addition she's set to appear in Spike Lee's "Oldboy" and 2014's remake of "Godzilla." The role in Whedon's powerhouse franchise would rocket the 24-year-old actress straight to the A-List.

Unfortunately, Whedon has not confirmed any casting rumors and the actress denied any knowledge of the project in an interaction with fans on Twitter, according to the Inquisitr.

How the films handle both Scarlet Witch, also known as Wanda Macimoff, and her brother Quicksilver will be a creative and legal hurdle. Most of the Avengers team's powers are rooted in science and technology. The new duo, however, are mutants. Scarlet Witch's father in the comic books is arch X-Men villain Magneto. Fox currently owns the rights to all things X-Men and thus, the two will need to find another way to explain why one can move with super speed and the other can manipulate probabilities with her mind, according to MTV News.

Changing up the characters' back-stories from the comic book won't be something new to the project. Ultron, the villain of the film, is a man-made creation in the comic books created by Ant-Man. Unfortunately, Ant-Man won't be introduced into the Marvel film universe until after "Age of Ultron" hits theaters. This means his back story will also have to be amended from the comics.
