Reynolds also had a close relationship with Jack Webb. He had the lead role in Pete Kelly's Blues (1959), and had a memorable guest spot as "Sgt. William Riddle" on Dragnet 1967 (1967). His last role was on the Webb-produced series, Project U.F.O. (1978). His greatest success was as "Special Agent Tom Colby" (1967-1973) on Sur la piste du crime (1965).
