RopeOfSilicon have posted the official first image from Massy Tadjedin’s Last Night.

Selected to close this year’s Toronto International Film Festival, Last Night stars Keira Knightley, Sam Worthington, Eva Mendes and Guillaume Canet.

Last Night was written and directed by Tadjedin and is her first foray into feature film directing Tadjedin, having  achieved writing credits on John Maybury’s The Jacket and Mehdi Norowzian’s Leo previously.

Synopsis: Michael and Joanna Reed (Worthington and Knightley), are a happily married Manhattan couple, but after attending one of Michael’s business parties, Joanna notices a curious moment between him and his co-worker, Laura (Mendes). Nothing specific can be made of the incident, but each are soon tempted to stray. When Michael goes on a business trip with Laura, Joanna has an encounter with a past love (Canet).

Check out the first look image below, featuring Knightley and Canet:

Last Night will premiere at the Toronto International Film Festival in September. It does not yet have an official US or UK release date.
