In A Fistful of Dollars, a hero without a cause is trapped between two forces that are bigger than him, this allows him to play an interesting solution.

This is a summary of the plot by an IMDB user: "An anonymous, but deadly man rides into a town torn by war between two factions, the Baxter's and the Rojo's. Instead of fleeing or dying, as most other would do, the man schemes to play the two sides off each other, getting rich in the bargain."

All along the film, the hero keeps repeating this wonderful sentence, which is a bit like the chorus of the film: "The Rojo's on the right, the Baxter's on the left... and me, right in the middle."

The film is a remake of Kurozawa's Yojimbo. (Plot outline: A crafty ronin comes to a town divided by two criminal gangs and decides to play them against each other to free the town.)
