Robert Downey's Australian accent...

Batonga, batonga, batonga!

Not sure if its accurate, probably not but it was very entertaining. Bloood and Caaaarrnage. Waaaayne Gaaale

I know! When I first watched Natural Born Killers, I actually thought Robert Downey was Australian. His accent was very convincing.

I thought it was more South African.

I always thought that it was supposed to be way over the top. Like an American trying to emulate a Robin Leach type voice over and just chose Australia instead of England.
