Nighty Night is a BBC black comedy television sitcom starring Julia Davis. It was first broadcast on 6 January 2004 on BBC Three. Notorious for its dark humour, the show follows narcissistic sociopath Jill Tyrell (Julia Davis) alongside her moronic personal assistant Linda (Ruth Jones). Jill learns that her husband Terry (Kevin Eldon) has cancer. She uses this to manipulate new neighbour Cathy Cole (Rebecca Front), who suffers from MS, and her husband Don (Angus Deayton), a doctor and the man with whom Jill becomes increasingly obsessed.
