What 2007 documentary about detainee abuse in Afghanistan won the Oscar?

The 2007 documentary about detainee abuse in Afghanistan that won the Oscar is Taxi to the Dark Side.

Directed by Alex Gibney, the film centers on Dilawar, an Afghan taxi driver who died in U.S. custody at Bagram Air Base in December 2002. It uses his case to examine interrogation practices, torture policy, and detention during the War on Terror.

The film premiered at the 2007 Tribeca Film Festival and won the Academy Award for Best Documentary Feature at the ceremony held on February 24, 2008. That timing can cause confusion: the film is a 2007 release, but its Oscar win occurred the following year.

A common mix-up is Standard Operating Procedure, another documentary about abuse during the War on Terror. It was nominated in the same Oscar category but did not win; Taxi to the Dark Side took the award.
