Chicago Reader review:
Though this sublime 1952 black-and-white masterpiece by Howard Hawks is usually accorded a low place in the Hawks canon, it's a particular favorite of mine—mysterious, beautiful, and even utopian in some of its sexual and cultural aspects. Adapted (apparently rather loosely) by Dudley Nichols from part of A.B. Guthrie's novel, this adventure stars Kirk Douglas and Dewey Martin as Kentucky drifters who join an epic trek up the Missouri River, along with the latter's uncle (Arthur Hunnicutt), an Indian princess (Elizabeth Threatt), and a good many Frenchmen. The poetic feeling for the wilderness is matched by the camaraderie, yet there's also a tragic undertone to this odyssey that seems quintessentially Hawksian—a sense of a small human oasis in the center of a vast metaphysical void.
Here (and above) is the trailer.
