The Flashing Blade (Le Chevalier Tempête) is a French television serial made in the late 1960s, which was broadcast in the UK on BBC children's television during the 1960s, with several re-runs in the early 1970s. Dubbed from French into English, the action was set in 17th century France, during a period of war between France and Spain. The dubbing was not exactly brilliant, so in the 1980s John Culshaw redubbed a comedy version (which is the one I remember best). In the '60s and '70s the BBC had a habit of buying childrens programmes from European countries which were then very badly dubbed into English - often to hilarious effect.
