The trailer for Lynne Ramsay's latest, We Need to Talk About Kevin, has debuted at iTunes Movie Trailers and you can check it out in the player below.

A suspenseful and psychologically gripping exploration into a parent dealing with her child doing the unthinkable, We Need to Talk About Kevin is told from the perspective of Eva, played by Tilda Swinton in a tour-de-force performance.

Always an ambivalent mother, Eva and Kevin have had a contentious relationship literally from Kevin's birth. Kevin (Ezra Miller), now 15 years old, escalates the stakes when he commits a heinous act, leaving Eva to grapple with her feelings of grief and responsibility, as well as the ire of the community at large. The film explores nature vs. nurture on a whole new level as Eva's own culpability is measured against Kevin's innate evilness, while Ramsay's masterful storytelling leaves enough moral ambiguity to keep the debate going.

We Need to Talk About Kevin opens in a limited release on December 9th.
