Goddamnit, another great one gone. And she truly was one of the greats– effortlessly switching between the sorts of films worthy of being called art (DAY OF THE LOCUST, EASY RIDER, FIVE EASY PIECES, BORN TO WIN) and the sorts of films that you read about on this site (TRILOGY OF TERROR, IT'S ALIVE III: ISLAND OF THE ALIVE, INVADERS FROM MARS '86). She was capable of restraint and tremendous subtlety, but could go over-the-top with the best of them.
She'll be missed.
And I wish I had more Karen Black content, but here goes:
TRILOGY OF TERROR
HOMER & EDDIE
TALES OF THE CITY
