The project stars Melissa Benoist as Kara Zor-El, who escaped Krypton amid its destruction years ago. Since arriving on Earth, she’s been hiding the powers she shares with her famous cousin. But now at age 24, she decides to embrace her superhuman abilities and be the hero she was always meant to be. _Grey’s Anatomy_ alum Leigh will play Alexandra “Alex” Dancer, the confident foster sister of Kara. Fascinated by Kara’s powers from a young age, Alex developed a lifelong obsession with science, which inspired her to become a doctor. _Homeland_’s Harewood will play Hank Henshaw, a onetime CIA agent who now runs the Department of Extra-Normal Operations (DEO), which tracks extraterrestrial threats on Earth. If Hank’s name sounds familiar, that’s because he’s famous in DC Comics lore for being Cyborg Superman. Leigh and Harewood join the previously cast Benoist, Mehcad Brooks, Calista Flockhart and Laura Benanti. _Supergirl_ hails from _Arrow_ and _Flash_ executive producer Greg Berlanti and _The New Normal’_s Ali Adler, who will write and executive-produce with Sarah Schechter. Additionally, _Arrow_ and _Flash_ boss Andrew Kreisberg has signed on as an executive producer and writer on _Supergirl_.
