The cast list for CBS’ Supergirl pilot is pretty much complete now, with the announcement that David Harewood and Chyler Leigh are on board.

Homeland star Harewood will play Hank Henshaw, a onetime CIA agent, who now runs the Department of Extra-Normal Operations (DEO), which tracks extraterrestrial threats on the planet Earth. Fans of the comics will also know that Hank Henshaw is known in DC Comics lore for being Cyborg Superman.

Grey’s Anatomy‘s Leigh has been cast as Alexandra “Alex” Danvers, Kara’s foster sister on the show. Fascinated by Kara’s powers from a young age, Alex developed a lifelong obsession with science which inspired her to become a doctor. DC point out that “Of note to fans is the last name – longtime Supergirl readers know that “Danvers” is a last name which has occasionally been used by Kara in the comics.”
