The movie The Running Man (1987) is based on the Stephen King Novel The Running Man (1982).
The movie Das Millionenspiel (1970) is based on the short story "The Prize of Peril" (1960). (The movie The 10th victim (1965) is also based on the short story)
I have seen both movies, but I must admit, I did not read the stories. The movies have the same base story, a game show with a charismatic host where a candidate is hunted by some people and must try to survive, with strong media criticism.
Is there also such a strong similarity in the books?
Also, was King inspired by the older movie or short story, did he just copy the idea, or is the similarity by accident? Did King or the makers of the movie ever admit the influence of the older story/movie?
