The Six Million Dollar Man is an American science fiction and action television series, running from 1973 to 1978, about a former astronaut, USAF Colonel Steve Austin, portrayed by Lee Majors. After a NASA test flight accident, Austin is rebuilt with bionic implants that give him superhuman strength, speed and vision. Austin is then employed as a secret agent by a fictional U.S. government office titled OSI. The series was based on Martin Caidin's 1972 novel Cyborg, which was the working title of the series during pre-production.
