The Master of Ballantrae (1953) is a swashbuckler done right; from a book by R L Stevenson. Technicolor, of course, though not as luminous as in Scaramouche.
Fifteen years after Robin Hood, Errol Flynn is my age, which gives me an idea.
Being indecisive by nature, I arrange my Netflix list by date, but I could instead arrange it by the age of the director or lead actor. I could even write a Python program to probe the Internet Movie Database for that information; I wonder how long it would take to go through all the titles from title/tt0000001 (Carmencita, 1894: “The noted dancer, who goes through her graceful act exactly as she does at Koster & Bial’s, New York”) to title/tt0500200 (Bernadette Peters in Concert, 1998).
The castle of “Ballantrae”, by the way, also appears in an episode of The New Avengers (1976).
