I am frankly mystified by the comments of those who seem to find this film disappointing or inadequate, and even more by those who claim to prefer the 1956 version, which I consider to be inferior in every respect to the later version, except for some top quality performances by Donald Pleasence and Michael Redgrave in supporting roles.
We saw a leucistic Northern Flicker, learn more about here.
There is truth, and there is untruth.
