The Sydney Morning Herald suggested that Heath Ledger was made for the role because when he tried on Ned Kelly's original iron armour, it fit perfectly. Heath Ledger was quoted saying, "It was quite eerie actually ... we're the same height and the same body weight. He was skinny 'cause he was starving, I'm skinny 'cause I don't go to the gym."
Ned's original armor can be seen on display at the State Library of Victoria, Australia. Joe's armor is in the hands of a private collector. The National Trust (Old Melbourne Gaol) owns the armor believed to be Dan's. Steve's is with the Police Historical Unit (Police Museum in Melbourne).
The world premier of the film, which was in Australia, took place only 2 blocks away from where Ned Kelly was hanged.
The now blood-stained green sash Ned was given after saving a boy from drowning is on display at a museum in Benalla.
The Irish folk singer appearing in the film is Bernard Fanning.
