Levi Miller, who stars as Peter Pan in Warner Bros.' big screen adventure Pan, has signed on for a role in CBS' Supergirl, according to TV Line. The 12-year-old actor will portray Carter Grant, the son of media mogul Cat Grant, played by Calista Flockhart. The actor will make his debut in the show's fourth episode.

Carter Grant is described as sensitive and shy, essentially the polar opposite of his mother. As part of her duties as Cat's assistant, Kara Zor-El (Melissa Benoist) is tasked with babysitting the young boy, where he opens up and reveals his true feelings for Supergirl. Executive producer Greg Berlanti, who worked with the actor on Pan, had this to say about the casting in a joint statement with the rest of the show's producers.

"We loved working with him so much on Pan, we were excited to bring him into Supergirl's universe. He's an exceptional young actor and a part of the Berlanti Productions family. It will be fun for audiences, who we 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."

The site also reports that this character Carter Grant is independent of Cat Grant's son in the DC Comics, Adam Morgan. In the comics, Adam becomes embroiled in a plot with Toyman, a.k.a. Winn Schott, a character played by Jeremy Jordan on the hit series. It remains to be seen if that story will be adapted in the superhero TV series or not, but we'll certainly keep you posted with any other developments.

The series also stars Chyler Leigh as Alex Danvers, Mehcad Brooks as Jimmy Olsen, Laura Benanti as Alura Zor-El and David Harewood as Hank Henshaw. Dean Cain and Helen Slater are also starring as Kara Zor-El's foster parents, the Danvers. Levi Miller made his TV debut back in 2011, appearing in one episode of Fox's short-lived drama series Terra Nova.
