El Topo (1970)

A clad-in-black gunslinger known as "El Topo" (Director Alejandro Jodorowsky) and his nude seven-year-old son (Brontis Jodorowsky) head off into the desert and stumble upon a massacre where a lone survivor begs to be killed and is, mercifully put out of his misery by the young boy with a well-placed bullet to the chest. The pair discover the identities of the assailants – a vicious captain (David Silva) and his gang of ruffians – who are dealt with efficiently but not necessarily swiftly. After the confrontation, the gunslinger leaves his son with local monks and takes a woman named Mara (Mara Lorenzio), previously a sex slave for the captain and his men, as his prize. She convinces El Topo that she will only love him if he proves to be the best of his kind; he sets out to slay some of the finest gunfighters around, and while he is unable to defeat them through raw skill, he manages to outmaneuver, outthink, and outwit them. The journey sees the gunslinger set his path, a path that will lead him towards a future of great discovery, triumph, and remorse, all of which will shape his mind, body, and soul along the way.

Please Note: Playback of this H.265/HEVC encoded video file in VLC media player may cause problem (like Green Screen). A fresh install of the player or a new version can solve this problem. I strongly suggest you to download and install "K-Lite Codec Pack (Full or Mega version; totally free with WMP Classic)" on your system first and then try to play the file in VLC. If you still face the same problem, please switch your media player. I prefer "PotPlayer x64" and "WMP Classic HC x64". They're also free and filled with lots of stuff, just like your old friend VLC. Mac users please get help from the Internet and YouTube.MS18pp
