Prior to Ngor's death, a humanitarian organized was launched known as "Project Cambodia" to fundraise for Cambodian orphans as well as to rebuild the devastated Cambodian state.

After his death, the organized was dubbed, "The Dr. Haing S. Ngor Foundation", to honor him. "The goals of the Foundation include preserving the legacy of Ngor's accomplishments and human rights endeavors as well as the promotion of Cambodia's history and culture through education, activism and the arts".

Ngor was fatally shot by a trio of members of a gang known as the "Oriental Lazy Boyz" near his home in Chinatown (L.A.), California. The perpetrators were later arraigned and were found guilty of murder and convicted; however one of them petitioned for habeus corpus. It was granted and the decsion was reversed.

There was a conspiracy that the murder was an assassination order by the Khmer Rouge. No credible evidence was gathered to suggest it.

Ngor was cast to portray Dith Pran in the film, The Killing Fields, despite having no acting background. He would later receive an Oscar, Golden Globe, and Academy Award for Best Supporting Actor.

After that, he had a decent acting career. Ngor would star in several movies and television shows such as Heaven and Earth, Miami Vice, and The Iron Triangle.

Ngor was born in the city of Samrong Yong, Cambodia. He would later grow up to become a physician specializing in obstetrics and gynecology. Ngor was practicing his skills in Phnom Penh when the Khmer Rouge executed the mass evacuation of the capital. At the time he was married to My-Huoy who fled with him, but ultimately perished during childbirth.

On August 30, 1980 Ngor and his niece traveled to America where he would go on to write Haing Ngor: A Cambodian Odyssey, co-write Survival in the Killing Fields, star in the 1984 drama, The Killing Fields.
