Really smart questions about the character. She still intrigues me, and I saw Gingold, Hamilton, Resnick, Stritch, Angela Baddely in London (opposite a dull Virginia McKenna, post-Simmons), and someone I'm forgetting. I loved Margaret Hamilton (Kennedy Center) after all; she simply ignored her own Midwestern near-homeliness and presented the woman as a kind of crusty survivor, independent of her physical attributes. It was an understated but winning performance. If memory serves, deeply moving in act two for being resolutely devoid of sentimentality.
