Looks like CBS is following in CW’s footsteps by casting actors from previous iterations of popular superhero franchises in their upcoming Supergirl series. Just as John Wesley Shipp now stars on CW’s The Flash, CBS has just announced that Lois & Clark: The New Adventures of Superman star Dean Cain and Helen Slater, who played Kara Zor-El/Supergirl in the 1984 Supergirl film, will guest star on the pilot in unspecified roles.

Cain and Slater join Melissa Benoist (Whiplash) as Kara Zor-El, Mehcad Brooks (True Blood) as Jimmy Olsen, and the recently announced Calista Flockhart (Ally McBeal) as Catherine “Cat” Grant, who will be Kara’s boss. IGN also reported yesterday that we’ll be seeing some familiar faces from the comics too; David Harewood (Homeland) is set to play Hank Henshaw, the man who eventually becomes Cyborg Superman, and Chyler Leigh (Grey’s Anatomy) will play Alexandra “Alex” Danvers, Kara’s foster sister who works as a doctor.

In the new series, Hank will play a former CIA agent who now runs the Department of Extra-Normal Operations (DEO), a security agency that monitors extraterrestrial threats to Earth. Alex seems to be largely similar to her comic portrayal, and has been described as “confident,” “obsessed with science,” and “fascinated by Kara’s powers.”

We’ll continue to report on this story as it develops. In the meantime, keep your fingers crossed for Teri Hatcher.
