In the wake of "Martha Marcy May Marlene" and the recently-wrapped "Godzilla," Elizabeth Olsen is looking to continue her blockbuster-indie balancing act, as she's nearing a deal to join Joss Whedon's "The Avengers: Age of Ultron," TheWrap said.

If negotiations lead to a deal, Olsen would play the Scarlet Witch, one of two new characters being introduced in the sequel along with her brother Quicksilver, whom Aaron Taylor-Johnson ("Kick-Ass") is in negotiations to play, as first reported by TheWrap.

Olsen's potential casting was first reported by Bleeding Cool, which noted that she was offered the role after Whedon's first choice, Saoirse Ronan, passed.

The Scarlet Witch is the daughter of "X-Men" villain Magneto, though that relationship will be tough to allude to in "Avengers," as 20th Century Fox owns the rights to the X-Men franchise. The character has several superpowers, including ability to reshape reality. She does wear a cape and cowl, though her red tights aren't expected to make it from the comicbook to the bigscreen. Olsen would also be expected to don an English accent, according to one insider.

This isn't the first time Olsen has been linked to a superhero movie, as she has also been rumored for the role of Sue Storm in Fox's "Fantastic Four." A deal for "Avengers" is expected to take her out of contention for the female lead in Josh Trank's upcoming reboot, which is still searching for its titular quartet.

Olsen next stars opposite Josh Brolin in Spike Lee's "Oldboy" remake, as well as the Sundance movie "Kill Your Darlings." In addition to Legendary's "Godzilla," which also stars Taylor-Johnson, she has "Very Good Girls" and "Therese" on the horizon.
