Last month, actor Samuel L. Jackson confirmed that Elizabeth Olsen is playing Scarlet Witch in The Avengers: Age of Ultron, and just a few weeks later, Aaron Taylor-Johnson signed on to play her brother Quicksilver.

While doing press for her upcoming remake Oldboy, Elizabeth Olsen herself confirmed that she has signed on, and talks about reuniting with her Godzilla co-star Aaron Taylor-Johnson.

"We get to play husband and wife, and we get to play twin brother and sister. It's also fun because even though in Godzilla we play husband and wife, we don't have a lot of scenes together. I just love him. I love his family. I love his kids. I'm so actually work with each other. I think it's going to be fun."

When asked if she has seen any concept art or if she knows what her costume will look like, the actress had this to say.

"No, I just know about it. It's been talked about, and it's so fun."

She also spoke highly of director Joss Whedon, claiming that he might be too smart.

"He's very smart. He's too smart. He might be too smart. Some people are too smart for their own good, but he's amazing."

Production on this Marvel Phase Two sequel will begin in March 2014.
