Above, Tex Ritter and the uniformed Kenne Duncan in ROLL, WAGONS, ROLL (Monogram, 1939). Above, Kenne Duncan (as Ram Singh) and Warren Hull as Richard Wentworth appeared in THE SPIDER'S WEB (1938) and the sequel, THE SPIDER RETURNS (1941) cliffhangers. (Courtesy of Randy Laing) Above, Duncan as Ram Singh from his Columbia days in the SPIDER chapterplays. Above, from L-to-R are cowboy star Jack Randall, Kenne Duncan (in checkerboard shirt), Glenn Strange, Jack Perrin and George Chesebro.  Carl Matthews is in back with the neckhold on Strange.  From LAND OF SIX GUNS (Monogram, 1940). Above, an interesting lobby card from RIDING THE SUNSET TRAIL (Monogram, 1941), and from L-to-R are: Betty Miles, Tom Keene, Kenne Duncan, Sherry Tansey (James Sheridan Tansey), Earl Douglas, and Tom London. Earl Douglas' real name was Lou Yaconelli, the brother of sidekick Frank Yaconelli. If you look close, you might make out the moustached Arkansas Slim Andrews to the right of Keene's face. Can you spot the error on this lobby card - look at all the gunbelts and the holsters as they are on the left side. Apparently, the photo used in preparation of this card was reversed. Above, from L-to-R are Bud Geary, Hal Taliaferro (Wally Wales), Le Roy Mason (seated), and Kenne Duncan in VIGILANTES OF DODGE CITY (Republic, 1944). Above, the skeletal villain is about to administer a mind control serum to scientist Chambers (played by Kenne Duncan) in THE CRIMSON GHOST (Republic, 1946) serial.  I. Stanford Jolley's voice was used as the Crimson Ghost, but under the cape and face mask was Joe Forte.  On the left is henchman Ashe, ably portrayed by Clayton Moore of later LONE RANGER TV show fame. Duncan was still working in B-grade films in the late 1950s.  Notice he's billed second on this poster for THE ASTOUNDING SHE MONSTER (American-International, 1957), one of Ronald Ashcroft's productions.
