Looks like a Xerox of a Polaroid of the movie projected on a sheet. Says the description:

"Bulldog Drummond (John Howard) along with his pal Algy Longworth and fiancée Phyllis Claverling, come upon a severed arm that is still attached to a valise filled with high explosives. Their investigation put them on the trail of the evil Dravan Nogais, who has run off with the top secret formula for the explosives. As usual, Bulldog is aided by Colonel Nelson of Scotland Yard, and his trusty servant."

If this is indicative of the rest of other 99, this is going to be tough going. The quality of the print isn’t unwatchable, but everything else – the plot, the humor, the acting - is grainy. The science is grainy. John Howard plays Bulldog as a super-civilized sleuth, instead of the pug-ugly rough ‘n’ ready Briton he was supposed to be. He had one super-power, and that was the Zelig-like ability to take on the racial identity of anyone he meets:

 

 

Drummond’s Trusty Servant has a comic specialty, namely, having a stroke:

 

 

Inadvertent Documentary moments: rear-screen projection drive through London; nice shot of Piccadily circus in ’37.

 

 

Bov is probably Bovril, a British mood enhancer for anthropomorphic vegetables:

 

 

Bulldog suspends his wedding plans to go after the valise; apparently he did this several times in the series before he finally ran off with his "sidekick." Here’s the lovely lass he declines to wed. Phillis Claverling. Clavering, you say? Oy’ll bet she did, oy’ll bet she did. In this image she is  being consumed by the furry mandibles of a Madagascar Train Spider:

 

 

Or she's in her dinner fur about to sing. It's hard to follow.

If you’re wondering what Dravan Nogais looks like, wonder no more.
The second half of the movie takes place on a train, which is to say narrow interchangeable staterooms, and Nogais attempts to evade detection in the classic British fashion, which is to say by dressing up as a woman. Why, it’s Monty Python’s Terry Jones in an exciting new dramatic role:

 


It says something about England in the 30s that he thought he could get away with this.

Next week: another Bulldog Drummond movie. Rating for this one: five stars out of ten, although I suspect that scale will suffer many adjustments before we reach the end . . . of 100 Mysteries.
