Cecil B. DeMille's prologue fails to mention the great irony of the Battle of New Orleans: by the time it was fought, a treaty to end the War of 1812 had already been signed in London. However, word of the signing did not reach New Orleans until weeks later.
Anthony Quinn played the role of Beluche in The Buccaneer (1938). He did not appear in this remake, but was the film's director; it was to be his only effort as a director. He got it mainly because he was Cecil B. DeMille's son-in-law, but he greatly regretted doing it and complained for years about DeMille's endless interference. Quinn claimed that the true story was far more interesting than the cliche-ridden fiction DeMille favored, and that a screenplay he had prepared with writer Abby Mann was far better than the one he had been forced to use.
In his 1995 autobiography "In the Arena", Charlton Heston stated that he regretted being made to look much older than the real Andrew Jackson who was forty-six years old during the War of 1812.
According to Lafite's description of his first meeting with Jackson (written many years later), "Dominic Youx" was, in fact, Jean's eldest brother, Alexandre Lafitte, the man from whom Jean learned the buccaneer's trade.
Facts were changed to protect 1950s sensitivities. The real Jean Lafitte did have an affair with a Claybourne lady, but it was the Governor's wife, not his daughter.
