For English-speaking audiences, this French comedy could probably do with a glossary as well as subtitles; it helps to know that in France, a deputy is an MP, for example.
Its original title was Quai d'Orsay, after the Paris street where the Ministry for Foreign Affairs is located and which is, in Paris parlance, shorthand for the ministry itself, in the same way Whitehall means "the civil service".
The film started life as a best-selling graphic novel, whose writer worked as speechwriter to Dominique de Villepin when he was foreign minister.
But as a movie that pays homage to the American screwball comedies, even with the experienced hand of the prolific Tavernier on the tiller, it loses as much in translation as a subtitled Yes, Minister would in France.
This is despite an energetically motormouth performance in the title role by Lhermitte (Philippe Noiret's offsider in the bent-cop romp Les Ripoux almost 30 years ago and a popular casting choice for veteran farceur Francis Veber).
