We've had two impressively grim trailers for The Exorcist: Believer so far, and now we have an impressively grim clip, too!

In the footage above from David Gordon Green's revival of William Friedkin's 1973 horror classic we see Katherine (Olivia O'Neill), one of two girls who gets possessed along with Angela (Lidya Jewett), heading into church with her dress spattered red while she mutters about "the body and the blood" in an increasingly guttural voice. This one looks like it'll be truly horrifying.

The Exorcist: Believer arrives in theatres Oct. 6.
