<strong><em>We Need to Talk About Kevin</em></strong> Poster

A suspenseful and gripping psychological thriller, Lynne Ramsay's We Need to Talk About Kevin explores the factious relationship between a mother and her son. Tilda Swinton, in a bracing, tour-de-force performance, plays the mother, Eva, as she contends for 15 years with the increasing malevolence of her first-born child, Kevin (Ezra Miller)

Based on the best-selling novel of the same name, We Need to Talk About Kevin explores nature vs. nurture on a whole new level as Eva's own culpability is measured against Kevin's innate evilness. Ramsay's masterful storytelling simultaneously combines a provocative moral ambiguity with a satisfying and compelling narrative, which builds to a chilling, unforgettable climax.
