If you go back and watch Sofia Coppola’s “Lost in Translation” (2003), you’ll see that it’s lost none of its shimmer — that airily crafted blend of mood and moment, location and dislocation, all wrapped around the delicate tale of two souls who didn’t know they were lost until they found each other in the floating limbo of the Park Hyatt Tokyo. “On the Rocks,” Coppola’s seventh film as a writer-director, marks her creative reunion with Bill Murray, the costar of “Lost in Translation” (which Murray regards as his favorite of his own performances). And so it’s only natural that we go into it hoping for some older-and-wiser version of the same magic. When we first see Murray, he’s in the back of a chauffeured Mercedes, and he looks sensational. The eyes, with their hound-dog melancholy, still twinkle with mischief. There’s a touch more gravel in the voice, and the hair is now white, but it’s perfectly coiffed — and so is the Murray attitude of cynical zen joi de vivre.
