Il était une fois, une fois

Willy Vanderbrook, a brilliant French Belgian who has become a citizen of the world, is approached about the job of concierge at one of Paris's great 5-star hotels. Willy's application - rejected because he's too Belgian - forces him to carrying out a ridiculous and "royally" vengeful deception. By pretending to be heir to the Belgian throne, Willy and his gang set off a series of joyful events in the Parisian 5-star establishment. (imdb)
