Ballerinas who wanted the lead role in Miss Morozov’s performances had to push themselves to the absolute limit – and beyond. Most of her class was injured. Olga’s foot snapped clean off after she lost her balance during an en pointe. Natasha’s head hung limply to one side, having broken her neck when her partner dropped her. “Katia: Grand jeté,” Miss Morozov commanded. The brunette took a run-up and leapt into the air, legs wide. She botched the landing. Her torso split open from crotch to neck. She got up quickly, organs spilling out. After all: the show must go on.
