If the writers of Flash showed one thing, it’s that they appreciate the past history of the character in regards to it’s other TV appearance in the 90’s. So much so that they’ve cast four characters from that series, and brought them into the new one. Now, Supergirl appears to be doing something similar.
Dean Cain and Helen Slater have been confirmed to be cast in the upcoming CBS superhero crime series. Their roles at the moment are not known.
Cain portrayed Superman in the famous/infamous The Adventures of Lois and Clark, while Slater was actually Supergirl in the 1984 movie. This is not the first time either appeared in a DC TV show as a nudge to their past, as both appeared in Smallville.
