In 1974, for a programme titled "Curious Journey", he interviewed nine surviving IRA members from the 1916–23 period, i.e. the Easter Rebellion, Anglo-Irish War and Irish Civil War; they were Maire Comerford, Joseph Sweeney, Sean Kavanagh, John O'Sullivan, Brigid Thornton, Sean Harling, Martin Walton, David Nelligan (or Neligan) and Tom Barry. He was allowed to buy this last film back, as long as he did not mention who had commissioned it (the Welsh TV company HTV). At one point in his career, Griffith accused the anti-censorship group, Index, of censoring him by delaying the publication of two book reviews he had written for its magazine.
