When people think of horror films, slashers are often the first thing that comes to mind. The sub-genres also spawned a wealth of horror icons: Freddy, Jason, Michael, Chucky - characters so recognisable we’re on first name terms with them. In many ways the slasher distills the genre down to some of its fundamental parts - fear, violence and murder.

But some of the most terrifying horrors are those that take place entirely under the skin, where the mind is the location of the fear. Psychological horror has the power to unsettle by calling into question the basis of the self - one's own brain.

Body horror is one of the fundamental pillars of the horror genre and crops up in some form or another in a huge variety of works. There's straightforward gore - the inherent horror of seeing the body mutilated, and also more nuanced fears.

In the end I decided to indulge myself by picking eight of my favourite shorts, and choosing features to pair with them that would work well as a double bill. The pairs might be similar in tone, subject or style; some of the shorts are clearly influenced by their paired movie, while others predate the features.
