Entertainment Weekly shared that the film received praises after it was showcased at the Colorado-based fest on Saturday, September 2. The hall not only rose to give the actress-director a standing ovation, Anne Thompson of IndieWire also shares that there wasn't a dry eye in the house.

Based on the book with the same title written by Loung Ung, the Cambodian film revolves around the Cambodia genocide and the impact it had on a close-knit family.

Reviewing the movie, IndieWire's Eric Kohn told Twitter that she has delivered her best presentation yet. "Jolie's filmmaking constantly pushes forward with rapid-fire editing to suggest the passage of time, but nothing tells the story more than Sareum's face. The result is relentless and involving even when it stumbles," he writes.

Scott Feinberg of The Hollywood Reporter also shared similar views tweeting, "First They Killed My Father is Angelina Jolie's best directorial effort yet. Might well be a contender beyond the foreign language category."

These reactions are a big win for Jolie's directorial career given that her previous movies were not critically acclaimed. Except for her 2014 biopic Louis Zamperini biopic Unbroken, her other three movies were not well received.

Following the ovation she received by the audience at fest, Jolie took to the stage for a Q and A session where she revealed that the film making experience changed her life. "We're making this first and foremost for Cambodia," Jolie emphasized during the post premiere session.

Jolie explained her visit to Cambodia many years ago "changed my life." It was then that she picked up Ung's book and fell in love with it. After her life changing trip, Jolie returned to do humanitarian work, befriended Ung and adopted a Cambodian orphan, Maddox. The 16-year-old helped Jolie in the movie and was present at the screening with his other adopted siblings.

Jolie also revealed that she waited to make the film until Maddox was old enough so that he could be a part of it. "I wanted my son to know where he comes from," she added.

The impressive movie will be available for streaming starting September 15.
