The Ralph Smart-produced episode of "William Tell", "The Gauntlet of St Gerhardt", tells the story of the Tell family stalking and tormenting a party of Austrian soldiers who have kidnapped a friar (a character not unlike Tuck from "The Adventures of Robin Hood").
This adventure was scripted, as several of them were, by Doreen Montgomery from Ralph Smart's original story. In several respects, it resembles Ralph's famous Australian film "Bush Christmas" (1947) where a group of children hunt down a band of horse thieves. Ralph obviously drew from scenes in his earlier film, particularly the scene where the Austrians wake up to find their boots have been stolen forcing them to wrap their feet in rags for protection in the bush.
While "The Gauntlet of Sir Gerhard" alluded to the past film, the "William Tell" episode "The Prisoner", also directed by Viennese-born Australian Peter Maxwell, pointed to the future. In this episode, a youthful Michael Caine as the title character is referred to as Prisoner No. 6.
Now I wonder if Patrick McGoohan, star of another Ralph Smart-produced series "Danger Man", had borrowed this title for his sublime follow-up to "Danger Man" also called "The Prisoner".
I would like to think this is more than a coincidence because it adds a certain mystique to these wonderful series. But perhaps I am, like William Tell or Robin Hood, drawing a long bow.
