The crime series The Sweeney first burst onto British TV screens in 1975 and presented viewers with an irresistible mix of character drama and cops 'n' robbers action, leavened with blokey banter and pithy dialogue. It starred John Thaw as Jack Regan, a Detective Inspector with the Metropolitan Police's Flying Squad, a specialised team dealing with bank jobs and armed robberies. The title of the series was taken from "Sweeney Todd", a rhyming slang nickname for the Flying Squad. Jack Regan was a tough, old school copper, grappling with the changing world of police work in the 1970s. He was assisted by his loyal Detective Sergeant, George Carter, played by Dennis Waterman. But The Sweeney didn't mark Jack Regan and George Carter's first screen appearance. They had been seen first in the previous year's TV film Regan .
