The Legend of the Lone Ranger
The lead actor, Klinton Spilsbury (his one and only movie, if the imdb is correct), was dubbed by Stacy Keach (or was it James Keach?). Test audiences thought Spilsbury's real voice was lacking in authority to be believed.
It was released theatrically by Associated Film Distribution and may now be controlled by Universal, but the AFD stuff ended up with a whole bunch of different studios, so who knows where it resides now.
Aside from some beautiful photography by Laszlo Kovacs (the movie was directed by noted cinematographer William A. Fraker) and some good John Barry music, there's not much that 1981 audiences enjoyed. I had the dubious pleasure of running this theatrically to a nearly empty house every day for a week. It was a financial flop and critically slammed; AFD had a pretty good record that way: Saturn 3, Killer Fish, Green Ice, The Mirror Crack'd, and Raise the Titanic were all bombs.
