This episode served as the second pilot for the TV series and was made using a primarily Canadian cast and crew. The first unsuccessful pilot, made using an American cast and crew, became the episode, "Black Barrier". After the series was picked up by a Canadian network, the roles of Cavendish and Jean Leboeuf were eliminated and George Tobias was cast as Jonathan Banner's sidekick Pierre Falcon.
