Based on the best-selling book by William Stevenson, this three-part NBC miniseries begins in 1939, just before the outbreak of WWII. With his warnings of Hitler's treachery going ignored, out-of-power politician Winston Churchill (Nigel Stock) approaches patriotic Canadian industrialist Sir William Stephenson (David Niven) with an unusual request. Sir William is asked to use his own funds to secretly organize an Allied espionage network, to be set in motion the moment Hitler shows his hand. Joining in this covert operation is American president Franklin D. Roosevelt, who, risking possible impeachment, encourages Sir William to establish a training base for spies in Ontario. Other concerned parties include the courageous French expatriate Madelaine (Barbara Hershey) and Sir William's right-hand man Evan Michaelain (Michael York). Location-filmed in England, Norway, and Canada, A Man Called Intrepid was originally broadcast from May 20 to 22, 1979.
