One of Jack Hulbert's best films, a spoof of the Bulldog Drummond series. There is little point watching Bulldog Jack if you are a fan of neither Bulldog nor Jack, but the USP of this film is that it doesn't play fast and loose with the thriller elements. It works pretty well as a Drummond film, and the first reel could easily have been transplanted from any of the others, as the crooks try to sabotage Drummond's car. Jack Hulbert steps in with his immense amateur enthusiasm and endless self-belief, immune to any doubts about his detective ability despite setback after setback; this confidence was Hulbert's trademark, and in any of his films you knew it would get him the girl, eventually. Smart dialogue peppers most scenes, particularly the early scene in Drummond's flat where Hulbert tries to make sense of the mysterious goings-on: "who is this man Santini, and why doesn't he know what he's done?" Claude Hulbert steps in as Algy, perennial 'silly ass' of the Drummond films, a clever piece of casting which allows brother Jack a confidante who will not outshine him, however dim he is being; Claude's finest moment is in the climactic scenes on the underground. Ralph Richardson is a somewhat eccentric master villain (with bizarre hair and a "filthy hat"), and Fay Wray as the love interest plays it entirely straight, which was probably wise.
For the aficionado of either Bulldog or Jack, this is a great picture. It is one of Hulbert's best (he was always a stage star), and it's better than most straight Drummonds. This is at least partly because the thriller elements are taken seriously. The most obvious sign of this is that there are no songs in the film, still less dancing. Even in Jack's the Boy, in contrast, Hulbert gives himself a couple of charming numbers. The self-restraint pays off in spades here.
