The Good, the Bad and the Ugly (Italian: Il buono, il brutto, il cattivo, literally "The good, the ugly, the bad") is a 1966 Italian epic spaghetti Western film directed by Sergio Leone and starring Clint Eastwood as "the Good", Lee Van Cleef as "the Bad", and Eli Wallach as "the Ugly". Its screenplay was written by Age & Scarpelli, Luciano Vincenzoni, and Leone (with additional screenplay material and dialogue provided by an uncredited Sergio Donati), based on a story by Vincenzoni and Leone. Director of photography Tonino Delli Colli was responsible for the film's sweeping widescreen cinematography, and Ennio Morricone composed the film's score, including its main theme. It was an Italian-led production with co-producers in Spain, West Germany, and the United States. Most of the filming took place in Spain.
