Amores Perros

The quality of the DVD is superb, better than a cinema print.

The Trailer is sensational. We have become so used to the American method with the best bits of a movie being whipped across the eyes that when you see something like this, which has integrity, artistic sensibility and imagination, the craft of trailermaking takes on a whole new meaning. It becomes art.

Campaign Development follows the process of creating and choosing a film poster. All they show is the finished work, a series of designs leading to the UK and US posters. To an untrained eye, some of the early ones look better than the approved ones, being simpler and less cluttered with head shots.

Behind The Scenes is an arresting glimpse of filmmaking in Mexico City. It starts with director Alejandro Gonzalez Inarritu holding hands in prayer with his crew and hurling red roses into the sky. It ends with hugs, tears and white roses. The filming has a rough quality, dirty and dark and cramped. "It's a film that shouts all the time," Inarritu says. You watch the cars crash over and over again from different angles. It feels more real than the choreographed stunt work in Hollywood action pictures.

Deleted Scenes are interesting because they come with commentaries from the director and writer. The reasons they give for discarding good scenes, which include strong performances, are pragmatic and well-considered, but you feel for the actors. Inarritu spent seven months editing. Something had to go.

The three Pop Videos, two of which are directed by Inarritu, are unlike what you would expect on MTV. Like the trailer, they have an artistic quality that is quite beautiful.

Altogether, an excellent extras package.
