Da 5 Bloods certainly covers a lot of ground when it comes wrapping the movie’s fictional narrative around real-world context, from the flashback scenes set in Vietnam (including one scene where the soldiers learn about Martin Luther King Jr. being assassinated) to how the older veterans have been affected by current events in the United States.
The movie also throws in a lot of archival footage for audiences to absorb, particularly revolving around the civil rights movement in the late 1960s and how it addressed the experiences of black soldiers in Vietnam.
