This was Alexandro Jodorowsky's first recognised cult movie in the early seventies. Shot in Mexico, El Topo (or the mole in English) is a gunslinger (played by Jodorowsky), who, dressed completely in black leather, rides on his horse with his seven-year-old son through the desert; until they come across a massacre of people. One of the survivors tells El Topo who the culprits are, and he then takes on the guise of God and seeks revenge. There is a lot of surrealistic imagery from then on as Jodorowsky explores violence, racism and religious themes, but it is absorbing and the ending is very obscure. An easy candidate for a cult movie.
