Laurie Metcalf, umm. Jon, I'm still drawing a blank, just as I did when you've mentioned her before. I saw only a couple of episodes of Roseanne, and I've never watched Norm. But I did see all of the movies you listed...and I just plain don't remember her. IMDB didn't have her picture, but I found one elsewhere. It didn't help.
Of course, that isn't necessarily a drawback; Marian doesn't need to be high-profile as Holland does.
