Although The Godfather III got a positive reception, it didn’t live up to the quality of its predecessors, and one of its most criticized elements was unintentionally provoked by Winona Ryder. In 1972, Francis Ford Coppola brought Mario Puzo’s best-selling novel The Godfather to the big screen, becoming one of the greatest movies ever made and a landmark of the gangster genre, making way for a film trilogy. The Godfather II arrived two years later and served as both a sequel and prequel to the first movie, and the third installment arrived in 1990, which Coppola considers an epilogue.
