You may think the Divergent series can't get any more action-packed, but wait until you see Allegiant. Opening on March 18, the third installment of the YA movie series follows Tris (Shailene Woodley) "into a new world, far more dangerous than ever before." We're debuting an exclusive first look at the film's IMAX poster, and it is, dare we say, ravishing. We're getting serious Alfred Hitchcock/Vertigo vibes here. Check it out, and feast your eyes on the many posters for Allegiant!
