Watch the Absolutely Terrifying Trailer for M. Night Shyamalan’s New Movie ‘Split’

Let’s keep the lights on for this one.

M. Night Shyamalan is back again with another plot-twisting, overtly scary piece of cinema. 

Appropriately titled Split, the psychological horror movie follows Kevin (James McAvoy), a disturbed man with an alarming amount of personalities: 24, to be exact. After kidnapping a trio of girls, including one played by The Witch‘s Anna Taylor-Joy, the three captives attempt to reason with whichever of his personalities will listen, before his dormant (and deadly) persona emerges to rage war on everyone and everything.

Scared yet? 

Split hits theaters January 20th, 2017.
