David Remnick speaks energetically and eloquently to a silent, invisible NBC News interviewer about the late Boris Yeltsin; Remnick pronounces “Chechnya” just like a Russian (as far as I can tell), and Eustace Tilley provides quality control from his shoulder like either a stern angel or an impudent devil. If you leave the MSN site running after the Yeltsin segment but switch windows on your browser, as I did, you may be startled by some disgruntled snuffling; that’s the next segment, in which “for the first time ever, the rare and elusive Borneo rhino is seen on video in the wild”; its nostrils are impressive.
