You can tell it's an epic movie. No stupid whooshing noises added by the Salkinds distracting from the famous John Williams theme, but we get the slanted title crawl up from the bottom of the screen.

The Plainsman (1936)

I thought this was going to be a different movie. It was directed by
Cecil B. DeMille, hence epic. It's a pastiche of Western myths from
different parts of the 19th century, the advenutures of Wild Bill
Hickok, Calamity Jane, and Buffalo Bill Cody. Gary Cooper, Jean Arthur,
and James Ellison. Set in the aftermath of Lincoln's assasination, an
evil arms manufacturer with weapons it cannot sell decides to provoke
Indian uprisings by trading arms for buffalo hides to Indians who
promise not to shoot white settlers. They are represented by Lattimer
(Charles Bickford). Porter Hall plays the especially duplicitous McCall.

The unfortunate Helen Burgess, 19, plays Cody's wife. She had appeared
on stage, got an audition with the studio, then DeMille, who rarely cast
actors with no screen experience, auditioned her. She'd make a handful
of movies, then die from pneumonia during production of her final movie.

Jean Arthur was the best thing about the movie. Despite how short she
was and looking nothing like Calamity, she truly got into the role and
even learned how to crack a bull whip.

There's a big set piece of cavalry soldiers under siege for day by
Indians that gets dusty and foggy and makes it hard to see the action.

Unlike what Mel Brooks claimed, I didn't spot any Jews playing Indians,
just recognizeable character actors. Anthony Quinn turns up in a bit
part as an Indian and child actor George Ernest has an important scene
with Cooper at the beginning.

Much of the movie is fun, but with a sad ending. Entertaining if it's
about as factual as a biopic.

There was still a horse calvary unit organized under the Wyoming
National Guard that DeMille put in period uniforms, taken away from
their day job of rounding up Indians off the reservation, if that was
still a thing in the mid 1930s.
