Iconic Australian actor Michael Caton lives life to the full and makes no apologies for it. But at 78 he is aware the clock is ticking. In a candid interview, The Castle actor talks about the highs and lows of his career, the challenges of ageing and his lifelong friendship with fellow actor Jack Thompson. Australian Story joins him on a road trip across NSW where he meets farmers lobbying against a coal seam gas project in the north-west. For Caton, life is now imitating art, and nothing matters more than making an environmental difference during the time he has left.
