Colin Martin Douglas (28 July 1912 – 21 December 1991) was an English actor. Born in Newcastle upon Tyne, Northumberland, Douglas was educated at the Farm School in Cumberland. Following his elder brother Jock, he emigrated to New Zealand when he was sixteen, working in sheep farming and lumberjacking, but only stayed for five years before auditioning to study at RADA, after begging his father to let him return to try to become an actor. He did some time in repertory, but the Second World War halted his career. In the armed forces he went to Catterick and the Royal Military College, Sandhurst, became Captain and Adjutant in the Border Regiment, and served in the 1st Airborne Division.
