Originally the Man With No Name starred in Sergio Leone's Dollars Trilogy, formed by the films A Fistful of Dollars (1964), For a Few Dollars More (1965) and The Good, the Bad and the Ugly (1966) starring Clint Eastwood. Although it was not Leone's declared intention, as the films saw US release in 1966, they were advertised as a trilogy following the exploits of the same "Man with No Name", based on the fact that Eastwood's characters all share extremely striking similarities (which makes some doubt that it was not Leone's intention to make them a single character).
The Man with No Name's voice was provided by Eastwood himself for the English-language releases, while he was dubbed by the famous Italian actor Enrico Maria Salerno for the original versions.
Nothing is known about the origins of the mysterious Man With No Name. He has been an outlaw, a bandit, and a gun-for-hire, but retains a sense of honor that often finds him doing the right thing to help those in need in spite of his quest for personal gain. His adventures led him to become a wanted man by both the Confederate and Union forces of the American Civil War when he blew up a Union bridge and made off with a small fortune in Confederate gold.
He is shown as being slightly cynical, somewhat selfish and violent. He has been known to lighten up from time to time, showing a sense of humor through sarcasm, as well as being very compassionate to people he believes to be good, albeit he rarely meets any such people.
He uses Colt revolvers, one a Single Action Army (SAA), the other an 1851 Navy. Both are unique because of the snake like engravings on their handles. His main rifle is a Winchester Yellow Boy. He also uses a Sharps 1874 sniper rifle on occasion.
After the popularity of the three films there were several novels produced. Including the novelization of the Dollar Trilogy. There was also the novels A Coffin Full of Dollars, A Dollar to Die For, The Devil's Dollar, The Million-Dollar Bloodhunt, and Blood For a Dirty Dollar. The five books were all written by Joe Millard with the exception of A Dollar to Die For by Brian Fox.
In 2008 The Man With No Name got in his own comic with the same title with Dynamite Entertainment. The comic picks after the Dollar Trilogy films. A year later the comic The Good Bad and the Ugly made it's start also with Dynamite Entertainment.
