"Kumiko, the Treasure Hunter"
**1/2 (two and a half stars)
Filmmaking brothers David and Nathan Zellner conjure up the spirit of another cinematic brother act, the Coens, in "Kumiko, the Treasure Hunter," a comedy as dry and chilly as the Minnesota winter where it's set. Rinko Kikuchi ("Pacific Rim," "Babel") stars as Kumiko, a meek Tokyo office worker who becomes obsessed with finding the treasure she sees buried in a scene from a certain Minnesota-based movie. So Kumiko takes her boss' corporate credit card and flies to Minneapolis, armed with a well-researched homemade treasure map and meeting helpful Minnesotans along the way -- including a clueless deputy played by David Zellner (who directed). The Zellners' script creates some interestingly offbeat Coen-esque characters (though it must be a wild coincidence that Kumiko holds her pet rabbit the way Llewyn Davis carries a cat), but the execution is so deadpan that it barely registers a pulse.
