Roles outside of Star Trek

She had such a distinctive turn in at least one episode of Star Trek, I find it fun to see her in more normal roles like in Westerns. Her eyes are SO BLUE it makes it easy to spot her, but at the same time, she almost seems like a completely different actress.
Right now I'm watching her on Bonanza. Not watching too closely, but it's her alright, and she's very forthright with a lot of screen time and scenery to chew (haha).
But like I said, once you've seen her on Star Trek, she's pretty hard to forget.
