“Is it just me, or is he extremely articulate when he wants to be?” I’ve seen Aaron Schneider‘s Get Low (Sony Classics, 7.30) twice now, and have felt soothed and stirred both times. In the lead role as an ornery old cus, Robert Duvall scores in a way that recalls, here and there, his Oscar-winning turn in Tender Mercies. But Bill Murray, as a low-key funeral-home operator, and Lucas Black, as his employee, are just as spot-on.
