Arena presents two films by award-winning director Georg Troller , made for West German television's leading arts programme Personenbeschreibung. Sir Laurens van der Post is the subject of the first film. Known in the popular press as a friend and mentor of Prince Charles, Sir Laurens has devoted his life to drawing the world's attention to the plight of Africa's threatened tribes. The second film is a portrait of Texan criminal Albert Sample whose autobiography Racehoss tells the harrowing story of his 16-year sentence for armed robbery in a notorious Texan prison and subsequent rehabilitation.
