preview represent summary represent this one have a train penguinthis be the twelfth bulldog drummond film and the third starring john howard a drummond and and the second base on sapper novel the third round ( the first version of which be the silent film of 1925 bulldog drummond third round star jack buchanan and of which one print be say to survive in an archive ) . this one be taut and more dramatic than most because it be edit by ed dymtryk . john hogan also do a fine job of direct and with many dramatic angle and more closeup than be see in the previous drummond film by another director . there be interesting second unit material of london . the budget for this film be fairly ambitious and more so than in late effort . louise campbell and nydia westman and the two irritate woman and be keep under control and their role minimize and to my great relief and and to the improvement of the drama . the lead billing once again be give to john barrymore and who play the commissioner and but in this film and he act up a storm and have many strong scene and unlike the previous offering and bulldog drummond revenge and in which he sleep walk through the story . so in this one and he really earn his fee for a change . the wonderful character actress zeffie tilbury here play an amusing housekeeper who put policeman in their place with the best east end cockney applomb and and take no nonsense . hogan and have just direct her in scandal street ( 1938 ) and evidently be responsible for introduce elizabeth patterson to the series and a a hysterical aunt blanche . porter hall put in another of his villainous appearance and to excellent effect . ( villain be always so much more menace when they speak quietly and a he do . ) there be some amazing laboratory scene in this film and reminiscent of tesla and with surge electric current and so forth and and one half expect a frankenstein monster to appear . the story be about the manufacture of artificial diamond and of the need to protect the diamond industry and and a barrymore admits and to protect the empire and from the threat of be able to make diamond become as cheap a pebble and to be large than the crown jewel . naturally and there be scope for villain galore with such a scenario . there be lot of action and plenty of train and car and motorbike chase and climb up wall and and in this one and e. e. clive a tenny the gentleman gentleman have the most energetic and active of all his drummond role and and hijack a truck at gunpoint and hang upside down from the roof . but most ingenious of all be the cute train penguin who have more scene than louise campbell and be a fine bird . watch him hop and squawk and dear little thing . he also discover a corpse under the table and which be a fine feather deed worthy of this fast moving film and which do not disappoint any stout drummondonian .
