EXCLUSIVE: With six nominations and an Oscar win for 1983’s Tender Mercies already on his resume, legendary actor Robert Duvall has absolutely nothing to prove. But by taking risks in a raw and revealing turn as the title character in The JudgeDuvall landed his seventh Academy Award nomination — this time in the Supporting Actor category.

Playing opposite Robert Downey Jr, the veteran actor was in rare form, especially in a scene that required him to expose himself both physically and psychologically. Downey, who produced the film with his wife Susan Downey, was deserving of a nomination himself as a slick big-city lawyer who returns to his small-town roots and has to defend his own father,  the town’s well-respected judge, in a trial neither will be able to forget.

But Downey  was always aware this was a showcase for the 84-year-old star who made his film debut as Boo Radley in 1962’s To Kill A Mockingbird and continues to be one of our finest actors six decades later. When the opportunity came up to actually go one on one with Duvall in an interview setting, Downey simply could not resist. Here are highlights from that conversation in this exclusive featurette.
