JOY, RTE ONE, WEDNESDAY 9.35PM

On a mission Jennifer Lawrence delivers a typically accomplished performance in David O’Russell’s drama based on the true story of Joy Mangano, a New York air hostess and single mother who’s struggling to make ends meet until she has a brainwave. She invents a self-wringing mop, and after pulling some strings is given the chance to demonstrate her product on a TV shopping channel.
