Start the Revolution Without Me [1970, USA, comedy, DVDRip] MVO

1789, France. Louis XVI is king, with his queen, Marie Antoinette, at his side, somewhat. Louis summons aristocratic Corsican brothers, ruthless thirty year old twins Philippe and Pierre de Sisi, adept at swordplay, to his court in a matter concerning the arranged marriage of the Duke d'Escargot to Princess Christina of Belgium, the marriage solely for political purposes. Inept Louis is unaware that there are multiple plans underway within his court to use the de Sisis for their own benefit and against him as an internal revolution of sorts is in the works. Did you know that it's 1789 in France? Also underway unknown to those in the court is that a peasant revolt is in the works against Louis, with thirty year old long orphaned and somewhat dim twin brothers Claude and Charles Coupe used as their pawns. Have I mentioned that this takes place in 1789 France? The problem within this collective situation is that Philippe and Claude look exactly alike, and Pierre and Charles look exactly alike, in the four having been born in the same doctor's office at the same time to two different sets of parents, one pair of babies purposefully switched in the doctor and his assistants not remembering which set belonged to which parents, hence hedging their bets at fifty-fifty. Thus, cases of mistaken identity lead to things not quite working out the way anyone thinks or plans. It's 1789 France, did you know?
