“The Killing Fields” won 3 Academy Awards. Not exactly “completely ignored.”
True.
The Killing Fields (1984).
First They Killed My Father (2017). And that was an AJ passion project because of her adopted kids.
What else?
The S.E. Asian diaspora to the U.S. is amazingly neglected. If nothing else, I would think the U.S. emigre population is now large enough that filmmakers should look that way. The framing would probably include U.S. military and host families and communities in the U.S.
One of the Asian American actors, himself a refugee along with his parents, won an Oscar a couple of years ado — and gave the kind of tearful tribute to America speech that we used to hear from the Jewish emigres back in the day.
