In order to bring this important early sound era documentary into proper cultural and natural historic focus, one must bethink of the prodigious changes that have altered the face of Africa as well as its humanity and fauna during the more than 70 years since the film's production. One can only imagine the reaction of a 1930 audience which viewed the extraordinary events presented and filmed by Colorado-based explorer Paul Hoefler, including the death and mealtaking by a family of lions of one of Hoefler's expeditionary native assistants, total decimation of the expedition's surrounding flora by a massive winged horde of locusts, and remarkable animals and people of many varieties. Narrator Lowell Thomas' somewhat casual comments of events that could not have been greeted in such cavalier fashion at the time they occurred can be offputting, and his attempts at whimsy consistently fall as flat as the veldt being traversed, but withal the narration provides a raft of historically fascinating data. Hoefler's book of the same title, published shortly after the release of the film, differs insofar as the expedition actually travelled from east to west, rather than the reverse, but for purposes of visual impact actual events were edited in order to produce dramatic action.
