"Injun Trouble" is a very difficult film to rate--so I'll skip a numerical rating for this one. This is because the ending to the film was missing--a common problem with old silent films. Because these movies were made on nitrate film stock, which tends to deteriorate quickly over time, many old films only exist in bits and pieces. So, having almost all of "Injun Trouble" is actually rather fortunate.
The film begins with a Confederate officer being given orders to go undercover as a spy. His task is to prevent the Union from gaining access to gold from their mines in Nevada. However, this plot soon vanishes and the film seems to meander terribly. First, the hero is inexplicably captured and allowed to escape by the Union troops and ultimately he is captured by a group of Indians--who he teaches how to dance in the final portion of the film.
While the film has some amusing moments, for the most part it's terribly unfunny and episodic. To make things worse, the Indians are total idiots--and ride their horses around the covered wagon repeatedly---allowing them to be easily shot. Overall, it's a film best suited for die-hard fans of silent comedies---all others would probably find the film a bit dull.
