Cast Bruce Beeby as Manning, an MI5 official Don Crosby as the scientist, Dr Arthur Ross Winifred Green Betty Lucas Reg Lye Production The show was rehearsed for 44 hours. ABC's head of drama Neil Hutchinson told the press: TV actors have to forget all the traditions of the stage. Theatre audiences accept without question the convention that allows an actor to say 'I love you,' projecting his voice so that it is heard in the back row of the gods. Televiewers in their own living rooms won't accept this convention at all. They don't want to hear his emotions shouted at them; they want to see and hear at normal pitch. They also have to learn to cut down on gestures, to get their meaning across in the space encompassed by the eye of the camera. Desmonde Downing, one of the leading theatre designers at the time, did the sets. It was the TV debut of Don Crosby.
