Okay, I'll admit the casting in the film is REALLY strange--part of this is due to the plot, but I still had a bit of trouble believing Pierce Brosnan playing this lead (though he really did a pretty good job).
It's based on a true story of an Englishman who went to live with the Canadian Indians in the early 20th century. He claimed to be a mixed blood Indian. He was, in fact, so successful and well thought of that people came from all over to hear his lectures and be taken on his wilderness treks--even though he was not a mixed blood Indian and all his knowledge was from books or faked! The movie centers on this and what occurred when the hoax was uncovered.
The acting and settings were great and I really liked the film (once I suspended disbelief about Brosnan). It didn't get widespread distribution--probably because it was pretty cerebral--not a Bond film nor a romance--just a really odd film about a remarkable man.
