The Doctor

Revealing mistake: After King Arthur cuts off both the Black Knight's arms and both his legs, as Arthur rides away and the Knight is struggling on the ground, as he turns sideways you can see both his hands, held behind his back, and the depression in the ground where he is standing in a hole. This is how the effect was achieved.

Trivia: After they come to the conclusion about weighing the witch to see if she weighs the same as a duck, and then the scales balance, watch the scales after they drag her off to be burnt. The side which contained the duck is obviously loaded to start with, as it sinks lower than the other pan when there is supposed to be nothing on the scales. Hence the witch weighing 'the same' as the duck, and seemingly proving the villagers rigged the whole thing.

Trivia: Originally, the cast were going to ride horses, but then they realised they didn't have the capital to do so. They therefore came up with the idea of artificially creating the sound effect using empty coconut halves. They then decided that it would be a good idea to actually include the coconuts in the film, hence the film's long-running joke - it was never meant to be included.
