'Twyla Moves,' a new documentary by PBS American Masters, tells the story of the legendary choreographer and dancer, who got her start performing on subway platforms and rooftops in the 1960s. "If it was kind of level, it was fair territory," she says. We talk about starting an all-women dance company, mixing classical and modern dance, and choreographing dancers over Zoom in the pandemic. Also, TV critic David Bianculli reviews 'The Nevers' on HBO Max.
