CBS has already begun casting for its upcoming Supergirl television show. The series is being produced by Arrow and The Flash producer, Greg Berlanti, alongside Ali Aldler and Sarah Schechter. The casting department is currently looking for Caucasian females ages 22-26 for the role of Kara Zor-el/Kara Danvers aka Supergirl, as well as Kara’s foster sister, Alexandra “Alex” Danvers.
The premise for the show is as follows:
Kara at age 12 was sent from her dying home planet of Krypton to Earth, where she was taken in by the Danvers, a foster family who taught her to be careful with her extraordinary powers. After repressing said skills for more than a decade, Kara is forced to use her powers to stop an unexpected disaster. Energized by her heroism for the first time in her life, she begins embracing her abilities in the name of helping the people of her city, earning herself a super moniker along the way.
Kara’s sister Alex was partly jealous of her sibling yet also fascinated by her abilities, prompting Alex to learn as much as she could about alien anthropology, sociology and culture. Today, Alex works for a secret government organization and, alongside her heroic sis, will face many challenges, both mundane and super.
