CBS’ “Supergirl” Gets A Foster Sister

One of the more unexpected TV announcements in recent months has been that of a “Supergirl” TV series which CBS picked up in September.

Key people on The CW’s “Arrow” and “The Flash” are behind the “Supergirl” adaptation including producer Greg Berlanti and casting director David Rapaport who is currently seeking an actress for the title role of Kara Zor-El.

Now, TV Line has scored a casting breakdown for the series which confirms some plot details and adds some new ones, along with revealing one surprise character not in the comics which is being created for the series – a foster sister for Kara.

Like the comics, the show sees Kara Zor-El sent from her dying home planet of Krypton to Earth at the age of 12, where she is taken in by the Danvers family who warn her early on about using her powers. Having repressed her gifts for years, she’s now 24 and begins using her abilities to help those in need.

The foster sister is Alex Danvers, a smart and science-minded 26-year-old who resents Kara’s abilities. She studied all she could about alien anthropology, sociology and culture. She now works for a secret government organization.

Greg Berlanti and Ali Adler co-wrote the script and will executive produce alongside Sarah Schechter.
