For Jolie, who holds dual citizenship in Cambodia and adopted one of her children from there, the film was a passion project, according to The Hollywood Reporter.
"This means a great deal to all of us involved in making the film. To work with local artists to bring this story forward has been a moving and humbling experience," Jolie said in a statement.
"First They Killed My Father", was fully financed and produced by Netflix. The film is an adaptation of a memoir by Cambodian writer Loung Ung about her childhood experience of surviving the atrocities of the Khmer Rouge genocide. Untrained child actor Sareum Srey Moch has won rave reviews for her portrayal of the lead.
The movie is currently screening theatrically at all major cinemas in Cambodia.

The movie is also co-produced by Cambodian auteur and past Oscar nominee Rithy Panh ("The Missing Picture"), whose Phnom Penh-based company Bophana Production supplied production services to the project.
"And because this history doesn't belong only to the Cambodia people; it is universal. Cinema also is a way to talk about the resilience and dignity of human beings," Panh said.
