Legend of the Lone Ranger [1981]
This much-maligned big-screen version of the well-loved radio and TV show stands as one of the rare cases in which the entire performance of one of a film's stars was redubbed by another actor. (For the others, see Andie McDowell in Greystoke and Harvey Keitel in Saturn 3.) In this case, it was youngster Klinton Spilsbury (and whatever happened to him?), cast as the famous Texas Ranger, ambushed by villains and left for dead, only to return with silver bullets, a horse named Silver, a mask, and a Native American sidekick named Tonto (Michael Horse) on a one-man mission for justice. In this film he battles a vicious group of bad guys led by a flinty-eyed Christopher Lloyd. Spilsbury's every line was redubbed by James Keach. Despite a critical drubbing, this is actually a better Western than you would expect, given its long-sullied reputation. --Marshall Fine
