Most Underrated Actress Ever
I'm not really a star trek fan or anything (I haven't even seen her in the show, although I realize it's often what she's known for). But I've always hated it that she hasn't been better recognized as she's done consistently great work her entire career, but she nevertheless isn't really a recognizable name to most people (beyond maybe rabid star trek fans).
I first discovered her after seeing her in the Brothers' Quay adaptation of "Jakob Von Gutten" (Institute Benjamentia). She's the best thing about that movie. Seriously. I used to watch the dream sequence scene where she goes mad while the students are humming in the background over and over.
Now it's on youtube, though, so you can watch it for yourselves:

Then I saw her in Guy Maddin's "Twilight of the Ice Nymphs" -which admittedly is his absolute worst film -but she does the best she probably could with the role given her in it (Guy Maddin mentioned in an interview that she was suppossed to be in "Cowards Bend the Knee," but she had to drop out over a scheduling conflict -which sucked, as that was a much better film than "Twilight").
I kind of forgot about her until I saw her guest spot on "Deadwood" -which was amazing enough that I finally got around to looking her up.
So, basically, I just think it sucks that she doesn't get more higher profile work.
