I haven't seen the movie, but I read the book after having heard about the "Lunatic Line" -- the name given to the railroad from Mombasa to Uganda through Kenya. The book and the movie tell the story of how the construction of a bridge across the Tsavo River was imperiled by incredible attacks by two giant lions who killed 130 workers, and how they were heroically dealt with by the chief bridge builder and a white hunter. All it all, it is a book filled with excitement and awe. Assuming it's all true, it's an incredible story. Now, I gotta go see the movie.
