When the Lone Ranger calls out "Hi Yo Silver, Away" it is the voice of Earle W. Graser, the radio's Lone Ranger, heard and not the voice of either Lee Powell or Billy Bletcher. His recording of this signature cry was used even after his death and Brace Beemer had become the Lone Ranger.
In Spanish, Tonto means "stupid," so in Mexico the character's name is Ponto.
This is the movie that western actor Buck Jones tried to stop production on because he felt that Republic Pictures was stealing his ideas. He sued and lost the case. Buck Jones did a series of westerns that he rode a white horse named Silver and claimed in the lawsuit that he originated the yell "Hi-Yo-Silver". Jones made these movies before the Lone Ranger existed. They were made during the 20's and 30's. A few of the movie titles were The Lone Rider (1930) and The Texas Ranger (1931).
