The Molly Maguires is a 1970 American historical drama film directed by Martin Ritt, starring Sean Connery and Richard Harris. It is based on the 1964 book Lament for the Molly Maguires by Arthur H. Lewis. Set in late 19th century Carbon County, Pennsylvania, this social drama tells the story of an undercover detective sent to a coal mining community to expose a secret society of Irish-American miners battling exploitation at the hand of the owners. Partly inspired by a true story, the film portrays the rebellious leader of the Molly Maguires and his will to achieve social justice. The film score for The Molly Maguires was by Henry Mancini, a late entry in the production replacing a score by Charles Strouse.
