She was a regular on the first season of the well received drama House of Cards in 2013/2014. She was also a regular on a second show (Hostages on CBS) at the same time.
I guess that exposure (and her genre past, including having been in a Resident Evil and Underworld film) helped her get cast in the new Terminator film.
She was also set to be a regular in a tv show for ABC ("Exposed") but that wasn't picked up. Another show snapped her up though and she will be a regular on A&E's "The Returned".
So her career has really heated up!
