Trivia: The three Viking ships in the film were designed using blueprints for an actual Viking ship salvaged from the water and restored by a Viking museum in Norway. It turned out that the boats built for the film were too accurate, because the modern actors were taller than their historical counterparts. Every second oar hole had to be plugged so the modern men would have room to row with a full oar stroke. Otherwise, they would hit the backs of the oarsmen seated in front of them when pushing the oar handles forward to start each new stroke.
Trivia: The first film in the "Carry On" series. It had not originally been planned as the start of a movie series, but after its success at the box-office, producer Peter Rogers and director Gerald Thomas set about a further project with "Carry On Nurse" (1959), which was enormously successful. The "Carry On" series of films evolved after that.
Trivia: For close-ups of the giant marlin swimming near the skiff, Warner Brothers committed to building a giant, realistic, mechanical marlin with moving fins and tail, which was going to be deployed in actual open-ocean shots. Unfortunately, the first time it was lowered into Gulf Stream waters off the coast of Cuba, the elaborate mechanical marlin immediately sank and was never seen again. Thereafter, they used the much-less-realistic static marlin model that bobbed on the surface like a cork in a sound stage water tank (arguably the weakest scenes in the film).
Trivia: The Inn Of The Sixth Happiness tells the story of Gladys Aylward, an English missionary in China. The casting of Ingrid Bergman in the role was quite amazing, especially considering that Gladys Aylward was still alive at the time. Ingrid Bergman, who exuded glamour throughout the movie, was 5' 9" tall, had blonde hair and retained her native Swedish accent. Gladys Aylward was of rather plain appearance, stood a mere 4' 10" tall, had black hair and spoke with a cockney accent.Rob Halliday
