During the 1945 election she was making a campaign film about housing in postwar Britain, "The Way We Live Now", in which bomb-scared Plymouth played a major role, and it was there that she met Michael Foot, and was immediately captivated. After a four-year affair, necessarily clandestine as Foot was now an MP, the couple married in 1949. In the 60s and 70s, Craigie's ferociously protective, though often critical, support of her husband in his career as a left-wing firebrand, then a Labour minister and finally the leader of his party, often set her at odds with senior colleagues, notably Harold Wilson and Barbara Castle. But she would never have been happy to simply adopt the role of a political wife. The couple's mutual interest in literature and the arts made their Hampstead house a meeting place for artists and writers, one of whom, Arthur Koestler, it was later revealed, betrayed their friendship by raping Craigie. As the women's movement grew in strength in Britain during the 60s and 70s, Craigie became an inspirational figure for many of its leaders and an active participant in many feminist causes.
Most importantly, after meeting veterans of the suffragette movement about whose struggle she hoped to make a film, she embarked upon her monumental history of the fight to win the vote, "Daughters of Dissent". She and Foot also became regular visitors to Yugoslavia, where the dissident writer Milovan Djilas was a close friend, and her love of the country later led her to make her final film, "Two Hours from London", which documented the ordeal of the besieged city of Dubrovnik. Carl Rollyson was given access to the archive in Foot's Hampstead home, which contains Craigie's research notes, drafts of her journalism and scripts, and her correspondence with an array of major historical figures, ranging from prime ministers to writers, film-makers and artists. He interviews Craigie's daughter Julie as well as a range of her surviving friends, and Michael Foot talks with frankness about his marriage, the strains which were placed upon it by his own infidelities, and his pride in having shared the life of so remarkable a woman.
