A John Doe trailer has mysteriously popped up on YouTube. I say "mysteriously" since, Dennys Ilic, who worked on the film, was rather surprised to discover the wrap party trailer online. And he makes a good point that it could be taken down at any time. So, I suggest you watch it RIGHT NOW. Actually, maybe a half dozen times are so. ;)
Be warned, some of the footage is graphic, but, wow, there is some really impressive work from Jamie. And the Aussie fans can let us know how successful his accent is, though it sounds pretty good to my American ear.
