Dusty Ermine (U.S. title: Hideout in the Alps) is a 1936 British crime film directed by Bernard Vorhaus and starring Anthony Bushell, Jane Baxter and Ronald Squire.
An ambitious young detective from Scotland Yard is also on the trail of the forgery ring, and mistakenly comes to the conclusion that Jim Kent is still working as a master counterfeiter.
Vorhaus was so impressed by the performance of Margaret Rutherford in a theatre production he saw her in, that he insisted on casting her in the film, adding a new comic relief role to the original play especially for her.
Hagen had an ambitious programme of films for 1936, but his failure to secure effective distribution led to financial problems and the collapse of his company the following year during the Slump of 1937.
In the forgers' lair the printing presses shown are all made by the Adana company of Twickenham and completely unsuitable for the production of currency notes.
