Ralston helped create the television series
The Wild Wild West and wrote the pilot episode, "The Night of the Inferno". In 1997, at the age of 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." Ralston said he then created the Civil War characters, the format, the story outline and nine drafts of the script that was the basis for the television series. It was his idea, for example, to have a secret agent named Jim West who would perform secret missions for U.S. President
Ulysses S. Grant. Ralston's experience brought to light a common Hollywood practice of the 1950s and 1960s, where television writers who helped create popular series allowed producers or studios to take credit for said series, thus depriving the writers of any royalties. ==Outcome of court case==
