There’s a new trailer online for Lynne Ramsey’s We Need to Talk About Kevin. (Pay no attention to the French subtitles, unless of course you are or read French and want to read them.) Tilda Swinton and John C. Reilly star as the parents of a teenage old boy who goes on a high-school killing spree.

Based on the award winning novel of the same name by Rory Kinnear, We Need to Talk About Kevin marks the Scottish Ramsey’s first feature film since 2002′s critically acclaimed Morvern Callar.

Official synopsis: Eva (Swinton) puts her ambitions and career aside to give birth to Kevin. The relationship between mother and son is difficult from the very first years. When Kevin is 15 , he does something irrational and unforgivable in the eyes of the entire community. Eva grapples with her own feelings of grief and responsibility. Did she ever love her son? And how much of what Kevin did was her fault?

I love this trailer. Usually the music used gives us cues as to what the mood and tone are of what we’re about to see. If that were true here, coupled with the expression on Swinton’s face for the first half of it, I’d think this was a comedy of sorts. The mood and tone shift about half-way through and we know we’re dealing with something much darker.

We Need to Talk About Kevin also stars Ezra Miller as Kevin and will be in competition at the Toronto International Film Festival next month before opening in the UK on 21 October, followed by a limited (grrrrrr) US release on December 2. (Double grrrrrrr.)
