Bulldog Drummond's Revenge
http://www.imdb.com/title/tt0028670/ Most of the story-line revolves around a secret new explosive that a scientist has invented, which the villains would obviously love to get their hands on. Some of the better moments come when the main action interferes with Drummond's plans to marry Phyllis (Louise Campbell), while flustering the befuddled but ever-helpful Algy (Reginald Denny). John Barrymore is always good fun as Colonel Neilson, and he makes good use of his opportunities here, while E.E. Clive does likewise as the quick-witted Tenny.
