10 Best Horror Movies That Aren't Supernatural

10. Kill List (2011)

Coming from the twisted mind of Ben Wheatley (Sightseers and A Field In England) and co-written by frequent collaborator Amy Jump, Kill List is just as delightfully offbeat and twisted as you’d expect from this pair.

Centring around former soldier turned contract killer Jay (Neil Maskell), this bleak and nihilistic outing predominately focuses on Jay's struggle to reconnect with his family while he wrestles with his inner demons. Accepting a contract with his friend Gal (Michael Smiley) to earn some money, things take a strange and sinister turn.

After signing the contract in blood from a mysterious stranger, each of the three victims they're tasked to eliminate appear to recognise them and thank them before allowing them to take their life.

There’s something more insidious at play, and these friends are unwittingly in the centre of it all. It’s not until the shocking climax where the true horror is unveiled, revealing that a masked cult has been behind everything the whole time.

Without any real explanation for the events that have just unfolded, Kill List is a stark reminder that we may never know the bigger picture of what's happening around us.
