CBS reports that actor Levi Miller (Pan, Terra Nova) has been cast as Carter Grant, the son of Cat Grant (Calista Flockhart) on CBS’s upcoming ‘Supergirl.’

Miller will make his debut during the fourth episode. “As the son of a high-power corporate tycoon, 12-year-old Carter finds himself in the shadows, often keeping his thoughts and feelings quiet. That is, until his mother asks her assistant Kara, aka Supergirl, to start babysitting him. Over time, Carter will open up to Kara, disclosing his feelings on Supergirl.”

According to TVLine, Miller’s Carter Grant is independent of Adam Morgan, Cat’s son who appeared in the DC Comics, and ends up being killed by the Toyman, a.k.a. Winslow Schott.

“He’s an exceptional young actor and a part of the Berlanti Productions family,” said producer Greg Berlanti. “It will be fun for audiences, who we all know will fall in love with him as Peter in PAN on Oct. 9, to see his range with his turn as Calista Flockhart’s American son.”

Synopsis:

SUPERGIRL is an action-adventure drama based on the DC Comics character Kara Zor-El (Melissa Benoist), Superman’s (Kal-El) cousin who, after 12 years of keeping her powers a secret on Earth, decides to finally embrace her superhuman abilities and be the hero she was always meant to be. Twelve-year-old Kara escaped the doomed planet Krypton with her parents’ help at the same time as the infant Kal-El. Protected and raised on Earth by her foster family, the Danvers, Kara grew up in the shadow of her foster-sister, Alex (Chyler Leigh), and learned to conceal the phenomenal powers she shares with her famous cousin in order to keep her identity a secret.

Years later at 24, Kara lives in National City assisting media mogul and fierce taskmaster Cat Grant (Golden Globe Award winner Calista Flockhart), who just hired the Daily Planet’s former photographer, James Olsen (Mehcad Brooks), as her new art director. However, Kara’s days of keeping her talents a secret are over when Hank Henshaw (David Harewood), head of a super-secret agency where her sister also works, enlists her to help them protect the citizens of National City from sinister threats. Though Kara will need to find a way to manage her newfound empowerment with her very human relationships, her heart soars as she takes to the skies as Supergirl to fight crime.

Stars: Melissa Benoist as Supergirl, Mehcad Brooks as Jimmy Olsen and Lauren Benanti as Kara/Alura Zor-El, Calista Flockhart as Cat Grant, Chyler Leigh as Alexandra “Alex” Danvers, Jeremy Jordan as Winslow “Winn” Schott, David Harewood as Hank Henshaw, Dean Cain, Helen Slater, Peter Facinelli as Maxwell Lord, and Jenna Dewan-Tatum as Lucy Lane.
