A Nazi scientist poses as a murdered professor to carry out germ warfare tests
There is a memorable scene in this thriller whereby Mervyn Johns travels on the London Underground with the intention of releasing deadly germs. He baulks at the idea after seeing a passenger turn into a skeleton! The interior of the Underground train is thought to have only used a studio set though we do get to see the entrances to both Baker Street and Charing Cross Underground stations. The earlier scene at a country station used Bricket Wood on the St. Albans Abbey branch, masquerading on this occasion as ‘Gillington’. Although the platform and signal box are seen, the train again is a set. Two shots of real trains do appear though in the form a grainy shot of a passing express hauled by a GWR ‘King’ Class 4-6-0, and a very murky shot of a train arriving at London Paddington in which it is impossible to identify the loco at the front.
