"Are ... you ... ready?" Samuel L. Jackson asks in a new international trailer for "Glass." To which we say: hell yeah!

The trailer is set primarily in the mental institution that houses Jackson's brilliant but unstable Elijah Price, Bruce Willis's "Unbreakable" David Dunn, and James McAvoy's "Split" villain Kevin Wendell Crumb. We see flashes of their sessions with Dr. Ellie Staple (Sarah Paulson) and just how much therapy isn't working on them.

Elijah, the titular Mr. Glass, uses that big brain of his to put a nefarious plan into motion, relying on the chaos sown by Kevin. But you know what they say about the devil you don't know.

The new trailer just adds to the anticipation of seeing M. Night Shyamalan's "Unbreakable" and "Split" universes coalesce.

"Glass" opens in theaters January 18.
