Christian Marquand
Captain Claude Duval
The Gay Cavalier was a 1957 British television adventure series set during the English Civil War and starring Christian Marquand as a fictionalised Captain Claude Duval. The series was made by Associated Rediffusion and shown on ITV between May and August 1957. In truth, Duval was a successful gentleman highwayman who came from France to post-Restoration England, but The Gay Cavalier portrayed him in heroic fashion. imdb.com
