Remington Steele is an American television series co-created by Robert Butler and Michael Gleason. The series starred Stephanie Zimbalist and Pierce Brosnan.  It was produced by MTM Enterprises. The first broadcast was on the NBC network from 1982 to 1987. The series blended the genres of romantic comedy, drama, and detective procedural. Remington Steele is best known for starting the career of Pierce Brosnan.  It also was a forerunner of the similar series  Moonlighting, and was also an influential part of television history in its own right.

Remington Steele's premise is that Laura Holt, a licensed private detective, opened a detective agency under her own name.  She then found that potential clients would not hire a woman. To solve the problem, Laura invents a fake male superior whom she names Remington Steele. Through a series of events in the first episode a former thief and con man takes the identity of Remington Steele. Behind the scenes, Laura stays firmly in charge.
