Director Đoan Hoang’s new documentary, Oh, America: My Brother, My Enemy, finds the second generation of filmmaker’s Vietnam war-divided family now divided by American politics, with her brother, deeply entrenched in a cult and QAnon conspiracies, joining the historic January 6, 2021 protests at the US Capitol. A follow-up to her award-winning Oh, Saigon, Oh, America shows the continuing effects of war and colonialism on families, even generations later.
