I once played a policeman in a film at bramall lane, no acting experience, but with me being six foot two it was qualification enough, However, it was neccessary for me to stand there in one spot for eight hours and with having a spinal disease it put me in terrible pain.
They wanted me to go again, but once was enough, I had to stand the yobos shouting hey mister, are you a real policeman, all the time. So I said to them step out of line and you will find out. They decided not to take the chance so everything turned out ok. For this I was paid the magnificent sum of £10. After that experience I don't think I shall pursue a film career.
