Possibly, Dianavan, but I think the dramatic frontier and western stories in the pulp fiction "penny dreadful" magazines and other printed material of the 1700's and 1800's may have got the ball rolling long before the movies ever existed. Certainly, though, the movies brought all that stuff to an even wider audience.

It was standard in comics (like Donald Duck, Mickey Mouse, Yogi Bear, Bugs Bunny, cowboy comics, etc...) for children in the 30's, 40's, 50's, and much of the 60's for pretty well all generic "Indian" characters to talk in a bizarre kind of broken English lingo, like...

"Ugh! That heap big white man. Where him from? Wait! Me gettum camera. Take-um picture."

Apparently this sounded like normal Indian talk to the average white person back then, but one can only wonder what the hell it sounded like to real Indians!

Being one of those whose heroes mostly were Indians, I just sort of rolled my eyes and put up with it, while reading everything I could get in the way of more serious writings on Crazy Horse, Red Cloud, Geronimo, Roman Nose, Pontiac and many others. I was in the Indian camp emotionally speaking from about age 4 or something like that...not because of any parental influence, but on account of some strong instinctive response in me right from the start. In that respect I was in a minority of one among the middle class kids I played with. They all wanted to be the "cowboy". This made me get used to being odd man out, and a loner...a feeling which has persisted to this day.
