They said: "A song on Euromantique, 'Love Games' . . . is based on a 1979 Star Wars: Episode IV - A New Hope (1977) rip-off, 'The Humanoid'. Not many people have seen or heard of this movie, but we were so inspired by it that we wrote a song. People will read the song completely different".

The name of the planet was Metropolis. The name had itself been the title of a famous b&w silent science-fiction film directed by Fritz Lang [See: Metropolis (1927)].

The Metropolis planet in The Humanoid (1979) replaced a former name of the planet, that being Earth. Ironically, in the film's closing epilogue, the planet is referred to as Earth and not as Metropolis.
