Hollywood director Frank Darabont has blasted US President GEORGE W. Bush's opposition to stem cell research, branding it "preposterous" and "uncompassionate". The Shawshank Redemption and Green Mile film-maker is a huge admirer of actor and Parkinson's Disease sufferer MICHAEL J. Fox, and is disgusted the Republican administration is blocking medical research which could potentially save thousands of lives. Darabont tells website MovieHole.net, "I'm very sorry he's dealing with the severe health issues he's been facing. He's very courageous. "Nobody deserves that... except maybe the a**holes in power in this country who are blocking stem cell research at every turn. Those preposterous, uncompassionate turds. "God, if you're listening, let them get sick, we'll see how fast the arguments go away and the funding happens."
