James McAvoy as one of his 23 characters in M. Night Shyamalan's Split.

The latest movie from the writer and director behind The Sixth Sense – M. Night Shyamalan – indicates that his return to form continues beyond The Visit and Wayward Pines, as Split prepares to wreak a terrifying – and controversial – multiple personality tale upon cinema audiences.

James McAvoy stars as Kevin, a man who holds some 23 distinct personalities within him. One of them (or, at least one, who knows) has succeeded in kidnapping three young women for whatever reason and it's up to them to escape before it's too late.
