The Legend of the Lone Ranger (1981)

When the young Texas Ranger, John Reid (Klinton Spilsbury), is the sole survivor of an ambush arranged by the outlaw leader, Bartholomew "Butch" Cavendish (Christopher Lloyd), he is rescued by an old childhood Comanche friend, Tonto (Michael Horse). When he recovers from his wounds, he dedicates his life to fighting the crime that Cavendish represents. To this end, John Reid disguises himself and becomes the great masked western hero, The Lone Ranger. With the help of Tonto, the pair go to rescue President Ulysses S. Grant (Jason Robards, Jr.) when Cavendish takes him hostage. We learn that Cavendish was an officer in the United States military before he was court-martialled and dishonorably discharged.
