 Since the armor the knights wore was really made of wool, and the  weather conditions in England being what they normally are, the  actors spent most of the shooting days being very cold and wet. To  make matters worse, the hotel where they were staying only had a  limited number of baths and hot water. At the end of shooting each  day, there was a mad dash to see who could get back to the hotel  first, and into some hot water. The Monty Python troupe all seem to  agree that they did not enjoy much of the filming experience for  this movie.
