Split trailer- Shyamalan strikes again with hair rising thriller

Well now, doesn't this look interseting.

The Sixth Sense and Unbreakable writer/director hit it big last year with the release of The Visit, a pared back chiller which saw him going back to his roots of chills and thrills. And his next looks even better.

Split might be the role of a lifetime for Scottish actor James McAvoy, and you'll have to watch the trailer to find out why.
