Nighty Night is a British dark comedy sitcom written by and starring Julia Davis. It was first broadcast on 6 January 2004 on BBC Three before moving to BBC2. Notorious for its dark humour, the show follows narcissistic sociopath Jill Tyrell – who manages a beauty parlour alongside her moronic, asthmatic assistant Linda – as she learns that her husband has cancer. She uses this fact to manipulate new neighbour Cathy Cole, a wheelchair user with multiple sclerosis whose husband Don, a womanising doctor, Jill has become obsessed with.
