Sarah Douglas, 68
Best known for her role as the supervillain Ursa in Superman 2, Sarah Douglas eventually returned to the Superman universe playing Jinda Kol Rozz, another antagonist. Douglas was so good at playing the bad guy that she continued the streak as Queen Taramis in Conan the Destroyer.
However, this doesn’t mean that she was always the antagonist; she even played Pamela Lynch, a conniving character with a soft spot in Falcon Crest. She is also renowned for her voice roles and most notable for her work in Superman and Batman Beyond. She is currently filming a 2021 documentary called In Search of Tomorrow.
