 He then worked briefly as a filing clerk and messenger for a film company in Victoria Street and film producer Jay Lewis in Wardour Street.From 28 April 1952, when he was called up to do his national service until 1954, he served in the British Army's Royal Fusiliers, first at the British Army of the Rhine Headquarters in Iserlohn, West Germany and then on active service during the Korean War.He had gone into Korea feeling sympathetic to communism, coming as he did from a poor family, but the experience left him permanently repelled due to the human-wave attacks practiced by North Korea and China, which left him with the sense that their governments did not care about their citizens.
