Dean Cain, who played Clark Kent/Superman in Lois & Clark: The New Adventures of Superman, and Helen Slater, who played Supergirl in the movie of the same name, will be in the CBS Supergirl pilot.
No details are known yet as to who they will be playing. As Alura, Kara’s Kryptonian mother, has already been cast with Laura Benanti, perhaps they are playing Jor-El and Lara, Kara’s uncle and aunt? (Interestingly enough, that’s the role Slater played on Smallville.) Or, maybe they are the adoptive parents of Kara on Earth, the Danvers?
Stay tuned and hopefully we will learn more soon.
