John Huston stated that working with his father on this picture and his dad's subsequent Oscar win were among the favorite moments of his life.
Walter Huston, father of director John Huston, won the Academy Award for Best Supporting Actor. John won for Best Director. This was the first father/son win.
In his Oscar acceptance speech, Walter Huston said, "Many, many years ago, I brought up a boy and I said to him, 'Son, if you ever become a writer, try to write a good part for your old man sometime'. Well, by cracky, that's what he did!"
On seeing the depth of Walter Huston's performance, Humphrey Bogart famously said. "One Huston is bad enough, but two are murder."
John Huston was fascinated by mysterious author B. Traven, who was a recluse living in Mexico. Traven approved of the director and his screenplay (by letter, obviously), and sent his intimate friend Hal Croves to the location to be a technical advisor and translator for $150 a week. The consensus is that Croves was in fact Traven, though he always denied this. Huston was happy not to query him on the subject but his then-wife Evelyn Keyes was certain Croves was the mysterious author, believing that he was continually giving himself away, saying "I" when it should have been "he", and using phrases that were exactly the same as those to be found in Traven's letters to Huston. Traven was offered $1000 a week to act as technical advisor on the film. It is known that "B. Traven" was a pen name, and Traven's true identity remains a mystery to this day.
John Huston: as an American tourist. This scene was directed by Humphrey Bogart, who took malicious pleasure on his director by making him perform the scene over and over again.
