In this Epic Saga Superman-Spin off used to be the Original Supergirl was released back in 1984 which stars Helen Slater who played Kara Zor-El (as Superman's Cousin) of Argo City from Inner Space in a search for the radiation source to her city and on Earth she becomes the Girl of Steel dressed in the Red & Blue Costume along with the skirt and cape.
In this SAGA remake Zac Snyder is working on the Superman Origins, and not for sure if “The Girl of Steel” may or may work out. Right now Henry Cavill is casted to play “The Man of Steel” first before the sequels move on. This is the SUPERGIRL (Casting Call) in case of something happens. Dont get to discouraged about the remake and here is the supporting fictional characters which doesn't apply to the SUPERGIRL comics, some are realistic or unrealistic
