PAN star Joins Supergirl

In a press release, it was announced Monday from CBS that a star from the upcoming Peter Pan film "PAN" will make a guest appearance on Supergirl.

Levi Miller will be cast as Cat Grant's song, Carter.

The young Australian actor will be making his debut in the fourth episode, performing with Calista Flockhart, who plays Cat Grant, and Melissa Benoist.

Miller will be the 12 year old, of the high-power corporate tycoon, who finds himself in the shadows, often keeping his thoughts and feelings quiet. That until his mother asks her assistant Kara, aka Supergirl, to start babysitting him.

Over time, Carter will open up to Kara and disclosing his feeling on Supergirl.

Producers of the series are thrilled to work with Miller throughout the season.

"We love working with him so much on PAN, we were excited to bring him into Supergirl's universe," they said in a press release. "He's an exceptional young actor and a part of the Berlanti Productions family. 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."
