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, "Steven O'Donnell has starred in many movies." is definitely correct, incorrect, or inconclusive?
