Eileen Heckart's performance
...was the best characterization of a drunk and upset woman I've ever seen. I mean, I really pitied her, not just her loss but her alcoholism. Her performance was raw and compelling.
I have to say that I admire actors who can do the same role hundreds of times and still put feeling into it, rather than coming across as automatons.
I did a couple of plays in school, and by the end I felt like I was on automatic pilot. The time would go by so fast, it's hard to believe I was still doing a good job at it.
