This is a prime example of when the book is far more entertaining than the film. The history of Rogers and Clark is fascinating; this film, on the other hand, is not all that attractive due to the harsh treatment of Native Americans who actually own the land of the Northwest Passage. Of course, the Eurocentric elitists of the New World believed all land in North America belonged to them. Spencer Tracy makes a fine enforcer of Eurocentric policy, and the supporting cast does a good job as well. History from the Hollywood perspective.
