After seven bandits invade her home, a widow hits the road with justice on her mind and five and three-quarters bodies in her wake. This astonishing neo-western begins with a sequence that will bring jaded grindhouse patrons to their feet, and then Marlina the Murderer in Four Acts blazes its own trail from there, incorporating some potent feminist themes along the way. Intoxicating viewing, really, with a director that knows when to pause for a languid long shot and when to slam forward into nastiness. Once heard, the soundtrack’s blending of traditional Indonesian folk songs and Ennio Morricone’s electric coyote yelps will never leave your head.

Marlina the Murderer in Four Acts screens tonight at the 44th annual Seattle International Film Festival, which is happening now through June 10. More recommended SIFF films here; and all SIFF films here.
