The Largest Land Carnivores in the World: The Polar Bear and Kodiak Bear. The largest living land carnivores are the Polar Bear (Ursus maritimus) and the kodiak bear, a Brown Bear (Ursus arctos) subspecies. Since they have similar body sizes, it is not clear which is definitively larger.
Hal Holbrook is great in this role and the mystery, while engaging is rather disturbing as McKenzie probes layer upon layer of political corruption during his investigation. One can't help but wonder about the political repercussions after the smoke cleared. It might have made an interesting film on it's own.
In 1967, Mark Twain Tonight was presented on television by CBS and Xerox, and Holbrook received an Emmy for his performance. Holbrook's Twain first played on Broadway in 1966, and again in 1977 and 2005; Holbrook was 80 years old during his most recent Broadway run, older (for the first time) than the character he was portraying.
