Rent Passport to Pimlico (1949)

Pimlico Remainers (spoiler). - Passport to Pimlico review by Steve

This popular Ealing comedy is an early draft of national myth making about London's response to the blitz. During the hardship that follows the war, the explosion of a dormant bomb reveals buried medieval treasure... and a deed which indicates that Pimlico isn't part of Britain at all, but a fiefdom of the Duke of Burgundy...

And therefore isn't subject to the austerity laws of postwar Britain. So the locals rip up their ration books and identity cards. The action is staged around the bomb site and the film builds a perverse nostalgia for the war years, when people pulled together. 

Given opportunity, leaders emerge. Stanley Holloway wants to use the windfall to develop social projects. Raymond Huntley turns his bank branch into the treasury. Margaret Rutherford shines as the excitable Professor who explains the historical back story. Ultimately the locals accept that deregulation leads to anarchy, and rejoin the UK.

There are the standard motifs of Ealing comedy, like the dreaded men from the Ministry, and the resourcefulness of the community, but the politics is muted. Though a shortish film, the interesting set up is overextended, and the satire is very gentle. However the ensemble cast makes it fun.  Don't miss those Brexit parallels!
