Chopper

Like many of the best films, CHOPPER isn't about one thing, and it doesn't tell one story. It's a film about life on the fringes of society, about the lasting effect of growing up in an unstable, violent environment; it's about mental illness and the less glamorous (and thus in film rarely depicted) aspects of the life of a gangster and career criminal. Most of all though, it's one of the most fascinating character studies I've ever seen with a tour-de-force performance by Eric Bana that is never less than superb. This was only the debut feature by director Andrew Dominik, but it's the meticulously crafted masterwork of a driven artist that deserves to be mentioned together with the best debut films by directors of his generation (it would take him 7 years to confirm with his sophomore film, the excellent THE ASSASSINATION OF JESSE JAMES BY THE COWARD ROBERT FORD (2007) that he wasn't a one-hit wonder). Once you've seen this raw, shocking, at times darkly funny portrayal of a sociopath you'll understand why it single-handedly launched Eric Bana's international career. A truly excellent film. 9 Stars out of 10.
