Body horror is a genre that has always been popular within the horror sphere, but the 21st century has seen the subgenre grow from the critical success of The Substance to the high-octane psychological work of Julia Ducournau. Yet, there is one element of body horror that may not have become a huge mainstream success, but has shown the way the subgenre has been pushed to the limits. These styles of movies often involve medical procedures where one individual is using others to perform experiments on the human body. Often met with disgust, these movies feature high on disturbing horror movie lists and include titles such as The Human Centipede, Tusk and The Skin I Live In. Two is a Spanish horror movie that slots perfectly into this style of filmmaking, seeing two strangers sewn together at the abdomen and forced to navigate their strange surroundings.
