Watch Diaz & Fassbender rave about Cormac McCarthy's The Counsellor script

The Counsellor was one of the most morally complex, disturbing and dark dramas of 2013.

Throw in an all-star cast (Cameron Diaz, Penelope Cruz, Brad Pitt, Javier Bardem and Michael Fassbender), an A-List director (Ridley Scott), and a critically acclaimed writer (No Country For Old Men's Cormac McCarthy), and it's guaranteed to stun.

We've got our hands on an exclusive sneak peek behind-the-scenes from its forthcoming DVD, in which Fassbender, Diaz and Scott rave about McCarthy's script, and the tragic consequences that unfold within.

The Counsellor is out on Digital HD on 10 March and Blu-ray/DVD on 17 March from Twentieth Century Fox Home Entertainment.
