9 of This Year's Oscar-Nominated Films That Are Based on True Stories

Director David O. Russell again teamed up with Jennifer Lawrence and Bradley Cooper for this biopic about Joy Mangano (played by Lawrence, who is nominated for best actress), the inventor of the Miracle Mop. The single mother of three balanced college and several jobs throughout the '80s, and in 1990, she developed the mop. Her business took off when she regularly began selling her product on QVC, and within a few years, she was a millionaire.
