The new upcoming CBS show will be written and produced by executive producers Ali Adler, Greg Berlanti, Sarah Schechter and Andrew Kreisberg.

"Supergirl" will be about the teenage girl's struggle as she tries to balance living in her new adopted home on Earth while trying to keep her powers on the down low, and "her awakening call to embrace her destiny as a hero."

New "Supergirl" casting rumors have also revealed that Helen Slater and Dean Cain would be part of the show. Dean was once Superman in "Lois and Clark: The Adventures of Superman," the TV series that came out in the '90s while Slater took on the role of "Supergirl" in the 1984 movie of the same name.

According to Nerd Reactor, the rumors claimed that these two former super heroes will be playing the role of Supergirl's parents in the CBS show.

The names of these two actors are now listed as Supergirl's adoptive parents Fred and Sylvia Danvers, on the official IMDB page.

"Supergirl" is said to kick off in the fall season of CBS.
