Update: It seems whoever posted this trailer didn't have permission to. It's been pulled from the web in recent days due to a copyright claim from the producers.
Not many non-Australian actors can do an Aussie accent. Most, like Quentin Tarantino in Django Unchained, maul it so horribly that it becomes comedy to us antipodean listeners. However the tide seems to be turning, slowly. Liev Schreiber (helpfully dating dialogue coach Naomi Watts) reportedly delivered a flawless Aussie accent in Mental and now Jamie Bamber absolutely nails it in the new trailer for John Doe.
That's not all he nails. Apparently Bamber plays some kind of serial killer, bringing vigilante justice to criminals who haven't yet paid their debts to society. Judging by the trailer, he inspires some kind of V for Vendetta style revolution with masked followers, although he himself is caught and interviewed by a stern-bearded Lachy Hulme.
No word as to a release date (we have a poster below that says 2012) but the trailer premiere suggests something is around the corner.
