Remember the 2009 Nicolas Cage sci-fi doomsday flick, Knowing? At the time it was released, most people thought it was pretty ridiculous, but six years later, it actually now seems like one of the LEAST ridiculous titles in Nicolas Cage’s filmography during the past decade. Anyway, since the production was filmed in Australia, a local 19-year old actor got himself a 15-second bit part as one of Cage’s students in a classroom scene. It turns out that bit player was none other than Liam Hemsworth.
