Jim Wants a Cookie
Jim (Bob Custer) and his friend Cookie (Harry Todd) manage to escape capture when the sheriff and his men come after them and decide their days as outlaws needs to come to an end. But going straight is not easy when they run into old friend and outlaw The Blanco Kid (Edmund Cobb) who causes them plenty of trouble when he tells their boss they are outlaws.
This review will be short as "Law of the Rio Grande" doesn't need or in fairness deserve much of a review as it is as basic as they come. But for those interested in old westerns it is worth watching purely to understand the genesis of the western. Watching this you get a real sense that director Forrest Sheldon was use to the static nature of silent movies whilst the actors were also more use to work in silent pictures with few having any real depth to their voice to make the dialogue sound real. On the subject of which, and this is where "Law of the Rio Grande" feels its age, you get long speeches which are simply full of cliches with an amusing one all about how all outlaws think they are invincible but there is a bullet with their name on somewhere.
What this all boils down to is that western entertainment "Law of the Rio Grande" doesn't offer a great deal, but as a glimpse at the genesis of the western and it evolving from being a silent movie this serves a purpose.
