I did not remember her being in Cheers, so I just watched the episodes again. What strikes me is the thing that made her such an amazing Captain -- Mulgrew has a commanding presence no matter what she is doing. She is one of those women that just takes charge of room, and simply by being there people pay attention to her. I'm sure her theatrical training helped to hone those skills, but part of it is an inborn trait that some people are blessed with. It is that part of her that carries over into every character she plays whether tv, film, or stage.
