Good deal. I think you'll enjoy it. Here's a little summary about the time period covered in "Four Years in Paradise":
"The second and longest trip, from 1924 to 1927, was partially supported by the American Museum of Natural History. During this trip the Johnsons spent much of their time in northern Kenya at their home by a lake they dubbed Paradise, at Mount Marsabit. This provided them the opportunity to film migrating animals in a variety of situations. In January 1927, they attempted to climb Mount Kenya. After reaching 12,000 feet, the Johnsons and several others developed high fevers and had to be carried off the mountain. Osa, who fell unconscious, spent six weeks recovering from pneumonia and high-altitude illness. This period is covered in Martin's "Safari" (1928) and Osa's "Four Years in Paradise" (1941), and in their film "Simba" (1928). http://www.scripophily.net/marjohafexco.html
