Oscar Goldman's background is revealed as an underwater demolition expert in World War II.
With the summer success of The Deep (1977) keeping alive the public's interest in soggy sea sagas, The Six Million Dollar Man kicked off its fifth season with a two-parter episode about killer sharks. The episode had its own movie poster, suggesting that the two episodes had been combined as a feature and released on home video, screened theatrically, or played on cable/free to air television as a single entity. The movie poster for it doesn't mention The Six Million Dollar Man television series it was made for. It has a credit block typical of a feature film and runs with the tagline: ''You are gripped again by horrifying shark terror!''.
