In between weeks when the DNC and the RNC will showcase two divergent portraits of Christianity in America, our guest is filmmaker Martin Doblmeier. The founder and CEO of Journey Films, Martin's latest documentary is Revolution of the Heart: The Dorothy Day Story.

We talk to Martin about Day, the blues, Cornell West, and what its like making a film with President Jed Bartlett.

How to describe Dorothy Day? Grandmother, anarchist, prophet, journalist, pacifist, saint? The FBI once considered her a threat to national security. Now the Catholic Church is considering her for sainthood.

REVOLUTION OF THE HEART: The Dorothy Day Story profiles one of the most extraordinary and courageous women in American history. She was co-founder (along with Peter Maurin) of the Catholic Worker Movement that began as a newspaper to expose rampant injustices during the Great Depression. It soon expanded to become a network of houses of hospitality to welcome the poor and destitute.

Over the years, Dorothy Day developed her understanding of how to follow the Biblical challenge to be “peacemakers” by resisting all forms of military intervention. She protested America’s involvement in World War II and was severely criticized. Day was arrested multiple times for protesting America’s nuclear buildup and she led nationwide resistance against the war in Vietnam.

Now nearly a century after they began, the number of Catholic Worker houses continues to grow and the newspaper is still speaking truth to power.

REVOLUTION OF THE HEART includes rare archival photographs and film footage plus interviews with actor/activist Martin Sheen, public theologian Cornel West, popular author Joan Chittister, Jim Wallis of Sojourners and many others.
