Ralston helped create the television series "The Wild Wild West" and wrote the pilot episode, "The Night of the Inferno". In 1997, aged 85, Ralston sued Warner Brothers over the upcoming motion picture based on the series ("Wild Wild West" was released in 1999). In a deposition, Ralston explained that, in 1964, he was approached by producer Michael Garrison, who '"said he had an idea for a series, good commercial idea, and wanted to know if I could glue the idea of a western hero and a James Bond type together in the same show."
