Amy Acker is going on the lam. The Person of Interest and Dollhouse actress has landed a leading role in Fox's untitled Marvel pilot about two ordinary parents who are forced to take their family underground after their children develop mutant powers.

EW has confirmed that Acker will portray one of the parents, Kate Stewart, who is grappling with her separation from husband Reed (True Blood's Stephen Moyer) when their lives take a dark turn.

Also joining the cast are Emma Dumont (Aquarius) and Percy Hynes White (Night at the Museum 3). Dumont will play Lorna Dane, a.k.a. the magnetic mutant Polaris, and White will portray a sensitive boy named Andy.

Previously reported cast members include Blair Redford, Jamie Chung, and Natalie Alyn Lind.

Matt Nix (Burn Notice) penned the action-adventure project, and X-Men filmmaker Bryan Singer is on board to direct the pilot. Nix and Singer are also executive producing alongside Lauren Shuler Donner, Simon Kinberg, Jeph Loeb, and Jim Chory.

The Hollywood Reporter first reported the casting news.
