Steele refers to the monkeys of Gibraltar as apes and states that if they leave Gibraltar, then England will fall. While tailless, these primates are in fact a species of monkey (specifically, the Barbary macaque); the actual legend is that if the monkeys disappear from the area, the territory will leave British rule.
Movie buff Steele says that Bogart's car in The Big Sleep slid off the road after running over tacks deliberately strewn there to get him into the hands of Canino. Never happened. Nobody mentions tacks. Marlowe got info from Harry Jones's girl about where Vivian was being held and deliberately slid off the road and let the air out of his tires himself after stopping first to make sure he had the right place. A movie buff would certainly know this important plot line.
