"Violence is the kind of thing that most people will (hopefully) choose to avoid in real life, but might well sometimes seek out when it comes to movies. There can be catharsis to seeing action play out on screen, especially if you're watching, well, an action movie… but the same could be said for films that belong to the crime, thriller, or horror genres, too. Fictional people have been hurting and/or killing each other since the dawn of cinema, basically, but movies started getting more graphic and visceral in more recent decades, thanks to censorship being relaxed and people around the world becoming less easy to shock. In the interest of shouting out those movies that are genuinely shocking, here's a ranking of some of the most violent films ever made, with selections made from a variety of genres to keep things interesting." - collider.com
