Undead is a 2003 Australian zombie science fiction horror comedy film written and directed by Michael and Peter Spierig and starring Felicity Mason, Mungo McKay and Rob Jenkins. It was then-relatively-unknown "Good Game" presenter Steven O'Donnell's first film role. Using only the above description and what you know about the world, "In 2003, Australian zombie movie introduced Steven O'Donnell's first role." is definitely correct, incorrect, or inconclusive?
