"Son of the Morning Star" made in 1991 starred Gary Coleman as Brevet Major General G. A. Custer covered those event pretty well for a TV movie.
I have seen this movie many times (Rosanna Arquette is playing Custer wife, right ? ), and it is quite accurate. However, it lack, according to me, the atmosphere of the plains that I could find in Dances With Wolves (which also has is bad parts.. like good indians, evil whites..).. And I think, mostly because it was done with less money. I would like it remake, with lots of more money and possibilities.
There was a 1912 film by Thomas Ince, rereleased in 1925 title "Custer's Last Fight" which was a pretty accurate recounting of the Little Bighorn.
This one I didnt see, but I am affraid that being that old, it's wouldnt be very realistic.. I mean, the battle scene, wounds etc.. too clean for me, I guess.
In little Big Men, the battle of Little Big Horn, is well rendered, and I even think it was filmed there.. the only bad part is that army mens and Custers are fools in this movie.. which wasnt the case..
Little Big Men is a nice movie, but is a hippie movie.. where all indians are good people camping out there and hurting nobody, and white men are evil as the devil himself..
It is interesting you remark about "the parallel life a US cavalry men and the one of a Cheyenne warrior from their youth to their end, fighting their last battle one against the other" since historian/author Stephen Ambrose wrote Crazy Horse and Custer, the Parallel Lives of Two American Warriors maybe twenty years ago. If you like history books I highly recomend it.
I'll try to find it on the internet, hoping that my poor english knowledge will allow me to get through it !
Thx for the tips !
