London, 1941. Amidst the rubble and disruption, vital war-work continues as scientists, soldiers, politicians and doctors all strive to keep the hopes of a besieged nation alive. But there's other work going on, too - work that might just seem a teeny bit trivial by comparison. A bunch of people making a feature film, for instance...

For the cast and crew, however, this is a very serious business. It's never been easy, getting a film made - and it's even more complicated when every draft of the script has to be approved by the Ministry of Information; when anyone, from star to tea-boy, can be called up at any moment; when travel's restricted, the studio's under fire, and the catering consists largely of spam fritters.

But there's a film to be made, a British film based on a true story of bravery and self-sacrifice at Dunkirk, with a nice touch of romance and comedy thrown in. Not to mention a hundred and seventy-five extras, one dog and an American. If this is to be their finest hour, the cast and crew of Just An Ordinary Wednesday will have to give much more than the usual blood, toil, tears and sweat.
