Intense, funny, tragic and cathartic are the words that may best describe Three Billboards Outside Ebbing, Missouri, a story of desperation, revenge, and determination featuring a fierce Frances McDormand as a divorced Missouri mother who pursues justice for her murdered daughter with steely resolve. She is supported by a stellar cast including Sam Rockwell and Woody Harrelson, and directed by Martin McDonagh. Elisabeth Sereda met them in Venice.
