Comanche funeral ritual from the movie "Eagle's Wing"

I just have seen the western "Eagle's Wing", and there is a scene of a Comanche funeral ritual. I wonder if someone can tell whether it is historically acurate or looks like based on some real ethnographic evidence or was counciled by some Comanche Nation Specialist and therefore it is close to real Numunuu funeral, or it is just some Hollywood made-up scene based on the screenwriter's imagination?

Here is the link to the movie, the scene starts on 22:40:

And the scene in a bad copy:

I really like the film but I never look to films for historical/ethnological/culutral accuracy.
