Scarlet River on AllMovie

In Scarlet River, Tom Keene plays "himself," a cowboy movie star, on location in the Wide Open Spaces for his latest epic. The locals chortle and guffaw at these picture people posing as genuine Westerners, but Keene proves his worth by rescuing Dorothy Wilson from villainous ranch foreman Creighton Chaney (aka Lon Chaney Jr.). Edgar Kennedy plays the flustered director, forever tearing out what little hair he has. The film-within-a-film sequences are staged with reasonable accuracy (future consumer advocate Betty Furness shows up as Keene's on-camera ingenue), while a few shots at the RKO commissary offer glimpses of studio contractees Myrna Loy, Joel McCrea and Bruce Cabot. The basic premise of Scarlet River would be revived in several future westerns by such cowboy stars as Charles Starrett, Buck Jones and Gene Autry.
