Mary Beth Hurt, the prolific stage and film actress who starred alongside Robin Williams in “The World According to Garp” and in Woody Allen’s “Interiors,” has died, her daughter announced Sunday. She was 79.“Yesterday morning we lost my mom, Mary Beth, to Alzheimer’s after a decade long battle with the disease,” Molly Schrader wrote on Instagram. “She was an actress, a wife, a sister, a mother, an aunt, a friend, and she took on all those [roles] with grace and a kind ferocity.
