Although Tarantino derived the name of his recent movie from Corbucci's Django, I bet he was inspired by this film for its story. Only here the bandits are the good guys; the bounty-hunters the villains. The hero is a sharpshooter named Silence, who lives up to his name: he never speaks a word throughout the film (and you thought Eastwood's Man With No Name was a tough sell). Kinski again proves his genius as the villain, but with all its unique elements and surprises, it's the baffling ending that makes this one of the best Spaghetti Westerns I've ever seen.
PS: Thank you, Toast. This has probably been your best movie recommendation ever.
