1977年，谭家明继《七女性》之后策划了另一个由他主导的片集系列《13》。命名《13》，是取西方文化里“十三不祥”之意；《13》每集独立，全部都是围绕凶杀、变态人物、不伦关係等偏锋题材。《13》原拟拍13集，但最终只拍了11集，全部由谭家明导演

In "13," visionary Hong Kong New Wave director Patrick Tam delivers his final TV work, an 11-episode anthology series that dives into surreal and darkly comic narratives. Although originally slated for 13 episodes, each standalone story explores eerie undercurrents of everyday life. Highlights include a couple discovering a corpse in their apartment, a schoolteacher uncovering the unsettling truth about her hosts, and a strained summer romance influenced by a mysterious housekeeper. "13" mixes black comedy with Tam’s iconic strange flair, creating a thought-provoking exploration of the bizarre hidden beneath the surface.
