Nicole Kitman, Errol Flynn, Peter Finch and David Gulpilil… they all are Australian actors who made their fortune in Hollywood. Australian talent is in fact very popular in the glitzy and cut-throat cinema business. Why is that? The book 'Cast Mates' looks behind the Hollywood curtain, from the Golden Age in the 1930s to the streaming wars of today. It follows the lives these four Australian actors and their cast mates and tells a story of how Australian cinema was founded, then faltered, before finding itself again.
