His latest, “One Battle After Another,” which is in the running to win some of the big awards on Oscars night, comes close to tossing us overboard from the beginning. Near the Mexican border, a ragtag crew of armed leftists liberates a group of immigrants held in an open-air pen. The action is pell-mell, rushed. When does it take place? Who are these American revolutionaries? White and Black warriors fight side by side, so they can’t be, as some reviewers have suggested, a version of the bomb-wielding Weather Underground of the seventies, which was overwhelmingly white. O.K., the movie is a fantasia, an interracial myth. Yet there’s something scarily authentic in these scenes. The immigrants are hunted by a military goon squad in full battle dress, terrifying enough in the morning-in-Falluja style of current ICE warriors. They bash through storefronts. Whenever the story is set, “Battle” is a movie of our moment.
