I remember only a little from it. A fellow makes his way through a city, repeating in some scenes, what someone in a previous scene said to him.
He runs into a cop for example, who curses at him and punches him in the stomach. In the next scene, the fellow says the same curse at someone else and punches them himself.
A band have him up on stage where he runs through all the comments people have made towards him again.
After that he has sex with a nurse and she gives birth. There’s not really much to those two scenes, but they round out what I saw of the film.
And yeah, the accents were from that part of the world (Australia, New Zealand) I won’t hazard a guess as to which was which, even after seeing a season of Flight of the Conchords. From the description above, I wasn’t able to get anything from Google either.
