SILVER SPURS, the 1936 Buck Jones western was helmed by his favorite director Ray Taylor, whose association dated back to the silent years at Fox Studios. Jones plays the wealthy rancher, Jim Fentriss, whose spread is besieged by cattle rustlers. The chief heavy, Art Holden, played by Robert W Fraser, is difficult for the hero to expose. After playing the waiting game for five reels, Jim swings into action (at long last!) in reel six. Buck Jones' leading lady, here as elsewhere, is Muriel Evans, who first gained popularity as comedian Charley Chase's vis-a-vis at Hal Roach.
