Erskine Caldwell at Work: A Conversation With Carvel Collins"ERSKINE CALDWELL had consented to be interviewed at his home on Twin Peaks in San Francisco immediately following last Christmas, when the film made from his phenomenally popular God’s Little Acre was in the final stages of cutting and preparation for release in the spring.God’s Little Acre has sold over eight million copies — more than any other novel written in our century. Other Caldwell novels— Tobacco Road, Journeyman, Tragic Ground, and A House in the Uplands — have sold between three and five million copies apiece in their American editions alone; and more than forty million copies of his books have been sold altogether."
