One of the great things about this renaissance of superhero television is the long memory of showrunners who bring back actors who made their mark in tights. Helen Slater played Supergirl in the 1984 theatrical release and Dean Cain famously donned the cape as Superman/Clark Kent on ABC's Lois & Clark: The New Adventures of Superman in the '90s. They will have guest starring roles in CBS's upcoming Supergirl series.
