HOLLYWOOD -- A harrowing film throwing the spotlight on US interrogation techniques at military facilities won the Oscars best documentary prize here Sunday.
Alex Gibney's "Taxi to the Dark Side" investigates the death in custody of a Afghan taxi-driver, Dilawar, at Bagram Air Base in Afghanistan in 2002.
An investigation into the death later found Dilawar had been repeatedly kicked and punched and was chained to the ceiling of his cell for days.
Gibney, who also produced hit documentary "Enron: The Smartest Guys in the Room", said in his acceptance speech that his wife had wanted him to make a romantic comedy.
"But honestly after Guantanamo, Abu Ghraib and extraordinary rendition that simply wasn't possible," the film-maker said before dedicating the film to Dilawar, and his own father.
?This is dedicated to two people who are no longer with us, Dilawar, the young Afghan taxi driver and my father a Navy interrogator who urged me to make this film because of his fury at what was being done to the rule of law,? said Gibney.
"Let's hope we can turn this country around, move away from the dark side and go back to the light," he said.
