This is one of my personal favorites. I gave it a 9 as I don't think that it's a perfect film, though it is very close. The acting is great and it's heart is in the right place. There are dozens of plot descriptions available here, so i will just tell you why you might love this film....
- a very honest and realistic portrayal of native Americans (by native Americans, like the excellent Graham Greene from 'Dances with Wolves').
- excellent location cinematography, it was filmed in the badlands.
- one of the most satisfying climactic scenes ever....it really feels good.
- the film has a fairly strong anti-government sentiment to it...(if you're all gung-ho for the US government, this film may not be for you).
- Thunderheart is based on actual events that happened on Pine Ridge Reservation in the 1970s. John Trudell, who plays Jimmy Looks-twice (the FBIs main suspect), was actually there! He is a real real-life Sioux activist whose character is loosely-based on Leonard Peltier.
Some other quick tidbits, look for David Crosby of Crosby, Stills, Nash & Young as a bartender in the bar room scene. I love the allegorical last shot of the film with Ray (Val Kilmer) in his car. Very fitting...which way to go? The whole film fits perfectly and usually I will say that many films wont appeal to every taste, however in the case of Thunderheart I will say this ....I don't know one person whose opinion I value who doesn't like this movie!
further note: If you like this one try watching the 1970 classic 'Little Big Man'.
