Before leaving camp on the first morning shooting I had been told to report to the hair-dressing departments tent, where I found the make-up men armed with electric clippers: 'I have to remove the hair from your chest.' 'Whatever for?' I asked, 'Orders.' It transpired that Clark , whose chest was completely devoid of hair, had always insisted that no other actor should appear on film exposing a hirsute breast. This included any member of the crew not wearing a shirt as well. He considered it a slight on his masculinity. We now had to return to the MGM Studios in London to shoot all the interior scenes. Someone must have pointed out to Ford that he had been thoroughly foul to me during the entire location shoot and when I arrived for my first day's work I found that he had caused a large notice to be painted at the entrance to our sound stage in capital letters reading "BE KIND TO DONALD WEEK". He was as good as his word - for precisely seven days. On the eighth day he ripped the sign down and returned to his normal bullying behaviour."
