10 Actors Who Appeared In Star Trek AND Battlestar Galactica

4. Kate Vernon

In Battlestar Galactica, Kate Vernon played Ellen Tigh, wife of Saul Tigh. If that seems like a rather diminutive description, then it's because it is. It is because it has to be. There is no way of doing justice to Ellen without spoiling, nay ruining, one of several of the greatest moments in contemporary television. Our hands are Tigh-ed.

Let's just say that Ellen is an infinitely complex character, one half of a mutually toxic couple flung back together after the Fall of the Twelve Colonies. Her introductory episode of the first season is appropriately called Tigh Me Up, Tigh Me Down. The rest is relativity. One thing always evolves in relation to another. Some things stay the same. The rest, if you haven't, you'll have to watch.

As for Star Trek, Vernon has so far had only one canonical appearance. She played 'Commander Valerie Archer' — a member of Species 8472 in deep disguise — in the Star Trek: Voyager episode In the Flesh. In the fan film Prelude to Axanar, Vernon was also Captain Sonya Alexander of the USS Ajax.

Double Battlestar Galactica alum Richard Hatch starred in Axanar, too, as Klingon Commander Kharn. Hatch was the OG Apollo in the 1970s, then political terrorist turned politician, Tom Zarek, in the 2000s. Ellen would have an… interesting relationship with Zarek in politician mode.
