This week we talk with actor, writer and director Matt Nable about his unlikely shift from professional rugby league and boxing into film and television, where he's played tough guys in shows such as Underbelly, Bikie Wars, The Dry and Mr Inbetween; penned his own screenplays and novels (from the comfort of his car) and recently, turned his hand to directing.

Nable talks about all this plus the benefits of being a military kid, coming to terms with his beloved brother's motor neurone disease, and his own mental health issues, in a conversation hosted by The Sydney Morning Herald senior writer Garry Maddox.
