Sergio Corbucci's often violent, often comic western is a classic. Franco Nero (as the Polak) is a self-serving gun for hire who finds himself aligned with Mexican rebels circa 1910. Tony Musante is the Simon Boliva wannabe who pays Nero to help him & his motley band stave off a pursuing army. Also in the mix is ruthless hired killer "Curley," played by Jack Palance. A fast paced, extremely well made spaghetti western with all the accoutrements of the genre: it's produced by Alberto Grimaldi; scored by Ennio Morricone; the supporting cast includes the likes of Giovanna Ralli and Eduardo Fajardo. Nero and Mustante have a lot of chemistry and Palance, looking oddly fey with black curly hair and perpetual grimace, is very menacing.
