Meet the young version of Melissa Benoist in the DC Comics adaptation.

CBS has cast its young Kara Zor-El.

Teenage Mutant Ninja Turtles' Malina Weissman has booked a key role in the network's DC Comics take on Supergirl, The Hollywood Reporter has learned.

The drama pilot centers on Kara Zor-El (Glee and Whiplash alum Melissa Benoist), Superman's cousin, who was born on the planet Krypton and escaped amid its destruction years ago. After arriving on Earth, Kara was taken in by a foster family, the Danvers, who taught her to be careful with her extraordinary powers (which she shares with her famous cousin).

Weissman, who played the young April (Megan Fox) in TMNT, will guest-star in the pilot as a young version of Kara, confirming speculation that the potential series will flash back to the DC heroine's early years as a child.

The young actress is repped by Paradigm and manager David Gardner.

Former Supergirl Helen Slater and ex-Superman Dean Cain will also guest-star in the Warner Bros. Television pilot.

Brothers & Sisters and Ally McBeal alum Calista Flockhart co-stars as DC Comics character Cat Grant, True Blood's Mehcad Brooks is set as Jimmy Olsen; Homeland's David Harewood is DC Comics character Hank Henshaw; and Grey's Anatomy's Chyler Leigh plays Alexandra "Alex" Danvers, the confident foster sister of Kara. Laura Benanti will recur.

Arrow and Flash's Greg Berlanti and his No Ordinary Family cohort Ali Adler (The New Normal) as well as Arrow and Flash EP Andrew Kreisberg will pen the script and executive produce the drama via Berlanti Productions' Warner Bros. Television-based banner Berlanti Productions' topper Sarah Schechter is on board to executive produce.
