The Two Doyles

Franklyn Farnum is coming out west with his wife and child to get a new start. Little does he know that his twin brother, also played by Farnum, has been larruping around the county, holding up a stage coach to steal a kiss from Louella Maxam (which pleases her) and throwing Indians off cliffs. The latter has the Injuns in hot pursuit, when he runs into his brother and family. During the fight, the wife is killed and the married one injured. Thinking he's a dead man, he tells his brother to save his brother. When he recovers, he is mistakenly arrested for his brother's crime (kissing Miss Maxam). Since he thinks he has no reason to live, he surrenders peacefully.

There seem to be a lot of Farnums in this movie, which wraps things up rather abruptly (thanks to some decent split-screen work), but this one was no relation to Dustin and William. He was a successful cowboy star during the silent era, but he took a couple of years off when talkies came in and and a result, his roles declined. From 1935 through his death in 1961, he appeared in hundreds of movies (including eight Best Picture winners) and dozens of tv episodes, but always as an uncredited extra.
