Butch Cassidy's Wild Bunch was one of the loosely organized outlaw gangs operating out of the Hole-in-the-Wall in Wyoming during the Old West era in the United States. It was popularized by the 1969 movie, Butch Cassidy and the Sundance Kid, and took its name from the original Wild Bunch. The gang was led by Butch Cassidy, and it included his closest friend Elzy Lay, the Sundance Kid, Tall Texan, News Carver, Camila "Deaf Charlie" Hanks, Laura Bullion, Flat-Nose Curry, Kid Curry and Bob Meeks. They would become the most successful train-robbing gang in history.
