Bogart, despite his image, loathed being on location preferring the studio. He was a New York stage actor and basically never left that world.
He gave one of his greatest performances in The Treasure of the Sierra Madre and loathed every moment of it. Huston must have been quite persuasive to get him into Darkest Africa for The African Queen.
He said he and Huston drank whiskey constantly all the way through the making of the African Queen, and that they were the only ones on the set who didn’t get dysentery.
