Kate Mara confirmed in interviews this week that she has been cast in the role of the Invisible Woman in the new Fantastic Four reboot, and that she is gearing up for the role.

The 31-year-old House of Cards actress said she was working out hard to prepare for the role, which may involve wearing figure-hugging costumes.

“I haven’t been told anything specifically yet, but that could change once we start filming,” she said when asked by an interview at E! whether she has changed her workout routine for the role.

Mara said she was not sure whether or not she would be wearing spandex as the Invisible Woman in the Josh Trank-directed project.

“I don’t know that that’s a thing,” she said.

“I think our film is going to be very different than the other one, which I never saw, but I know there was a lot of Spandex involved. I don’t know that they’re many Spandex suits in ours,” she said.

When asked about the comic book, Mara said:

“Well I don’t know very much about it, which is weird but true! Umm, all I know is that it’s going to be a very different take on the film, which people may not expect. I’m not really familiar with the comic books…I picked up a few when I got the part. I think we’re making a very grounded version of a superhero film. I trust Josh Trank’s vision as I was a huge fan of Chronicle.”

Mara also dispelled rumors she was cast as Michelle Knight, the Ohio woman who was kidnapped by Ariel Castro, in an upcoming film with a tweet she sent on Wednesday. Knight, along with two other women, escaped Castro’s home in May 2013 after years of captivity.

Mara posted a tweet on Wednesday denying the casting.
