S.H.A.D.O.

To defend against the aliens, a secret organisation called SHADO, the Supreme Headquarters, Alien Defence Organisation, is established. Operating under the cover (as well as under the premises) of the Harlington-Straker Studios movie studio in England, SHADO is headed by Commander Edward Straker (Ed Bishop), a former United States Air Force colonel and astronaut, who poses as the studio's chief executive.
