I liked ‘High Plains Drifter’ though I’m not a fan of westerns. I guess I like it because it’s not like the classic “clean” westerns my father grew up watching.
It was a running gag. Other folk said the same same thing to BJ several times until he says, “I swear the next man that says that, I’m gonna kill 'im!”
The next man was, of course, Dumbass (Richard Boone).
A lot of Westerns don’t feature Indians. The Cavalry and Wagon train films are subcategories within Westerns.
I’ve seen a lot of Westerns without any Indians.
At some point the movies changed to ‘sympathetic treatment’ of Indians. I don’t think the Indians who played the few important roles not filled by non-Indians were impressed. They probably weren’t thrilled with being left out of the movies altogether either.
Probably Cheyenne Autumn (1964).
Mid-'70s treatment of Indians:
Not a bad flick if you can overlook Mary Ann always being fully made-up.
In the silent era, movies were able to go the “Noble Savage” route, resulting in sympathetic films like The Silent Enemy, showing how tough life was for natives. Daughter of Dawn was a standard formula boy-meets girl movie, but done on horseback with an all-native cast.
The Silent Enemy proves that Native Americans may claim first-nations status but only second-most-shat-on. Its star, Chief Buffalo Child Long Lance was born African American Sylvester Clark Long (it seems that like sumo wrestlers, the longer the name, the more likely they’re non-native). The great American genius for self-invention almost always observed the color line, and unlike all the Italians, Jews and Levantines playing Native Americans, Chief Long Lance shot himself.
I remember during childhood asking why we didn’t see Indians in the Western towns. Normal store keepers or stablemen that happened to have a Native American bloodline.
Cahill US Marshall provided John Wayne’s character a supportive Native American friend. He was loyal, didn’t drink, and died helping his friend. It wasn’t cast with a Native American.
IMHO, all Westerns are B pictures until they prove themselves otherwise.
Why limit yourself to “B” movies?. Why not skip all the way over to the letter “Z”?
They Call Me Trinity is a good one.
Not sure this is a B movie, but for my money Hombre is the best western ever.
If we want to expand it to “Westerns that don’t get talked about a lot”
The Life And Times of Judge Roy Bean is one of the best movies ever made. (Featuring Anthony Zerbe AND Stacy Keach in small roles)…the soundtrack is so affecting, Tarantino used a small bit at the end of Once Upon A Time in Hollywood
Another would be The Long Riders which gets talked for its stunt casting, but is still a great film. That one has a Ry Cooder soundtrack.
That would be Neville Brand, who was also a highly decorated WWII soldier.
“'Ey, hombre! A compliment on your shooting! You put a hole in me! Whew. I never had a bellyache like this since I’m a little boy.”
I’ll add one, although you might consider it a B+.
The Rounders (1965) with Glenn Ford and Henry Fonda.
I good “buddy film”. And Glenn Ford makes great deadpan statements about what he’d like to do to their horse: “Sell him to a soap factory,” “Sell him to a dog food factory.”
How about “The Little Covered Wagon” (1930) by Sig Neufeld. It was actually a short feature with an all-chimpanzee cast.
When I asked for a “B” western, I never thought that B was for Banana.
Chimps are nothin’ compared to the cast of dwarves in The Terror of Tiny Town. You can watch the whole movie on the wiki page. And it’s a musical too.
If it hasn’t been mentioned yet, this “little picture,” another contemporary Western, was Kirk Douglas’s favorite:
Walter Matthau and William Schallert make a great team. 
I remember seeing “Lonely Are The Brave” for the first time only a few months ago on German TV (probably Arte TV). It was very good, and I especially remember an extended fist-fight between Matthau and Douglas. Also the only time I saw Walter Matthau in a Western, but he was very credible.
