What language are the Crow Indians speaking in Jeremiah Johnson is it really the language of the Crow Nation or is it from a different tribe?
The language spoken is certainly Crow, but it is obviously being
used by people who have only learned the phrases from an
instructor, not native speakers. The war chief "Paints His Shirt
Red" does not sound like a Crow, even though he speaks Crow words -
the accent and pronunciation is all wrong. The character was played
by Joaquin Martinez, a Mexican actor (why, when there must
be many genuine Crow actors?).
On the other hand the "Flatheads" (really Interior Salish) are
genuine and proficient Salish speakers, although the "wedding song"
they perform is really a funeral song since they did not have
"wedding songs" in their culture.
Despite its many faults the film is a fairly good representation
of life in the mountains at the time; one glaring error is the
completely inaccurate "Crow arrow" shot at Johnson early on by
Paints His Shirt Red, which is nothing at all like any genuine Crow
