With a provisional series title of The Mysterons,[35] Anderson and his wife, Sylvia, wrote a pilot script in August 1966.[36] This differed significantly from the final draft of the pilot episode. Initially, it was decided that the Mysteron duplicate of Captain Scarlet would be artificially resurrected by an advanced Spectrum computer rather than reviving naturally, and that thereafter he would no longer be truly human but a "mechanical man" akin to an android.[35] Another early ambition was for each episode to feature a guest star voiced by a well-known actor of the day. To this end, the role of the World President in the pilot episode was originally intended to be voiced by the American-born actor Patrick McGoohan.[37][38]
