The stunning Sundance documentary "The Stringer" challenges the authorship of the famous Napalm Girl photo from the Vietnam War.

After a half-century of public silence, a freelance photographer from Vietnam has asserted he took one of the most renowned and impactful photos of the 20th century — the image of a naked girl fleeing a napalm attack in South Vietnam that has long been credited to a staff photographer from The Associated Press.

The Times spoke to team behind "The Stringer" and an attorney for former AP photographer Nick Ut about the film's claims that Ut did not take the photo known as "Napalm Girl."
