I recently reviewed a 1940’s Ealing Studio’s classic for Flick Feast:
This quaintly enjoyable Ealing comedy is based on a real life incident from 1941 where the SS Politician, whose precious cargo included some 22,000 cases of whiskey, was wrecked off the coast of two remote Hebridean islands and intrepid locals salvaged thousands of the cases for themselves. Scottish nationalist Compton MacKenzie first wrote a novel based on the incident and then later co-wrote the screenplay for this film alongside Angus MacPhail.
