“Philosophus” is a screwball comedy about the egregiously self-righteous philosopher Voltaire and the bizarre escapades surrounding his flight from the court of Frederick II, King of Prussia, from whom he stole a sensitive, personal manuscript of poems. Determined to embarrass the monarch in revenge for an unfortunate falling-out, Voltaire finds his journey to France rudely halted in the city of Frankfurt by the intriguingly Hitlerian Baron von Freytag, representative of the Prussian King. Before too long, the Baron’s over-eagerness to obey his master’s wishes and the enormity of Voltaire’s ego combine to create a purely comedic kind of chaos, which becomes all the more ludicrous by the addition of a money-hungry German shrew, two slightly dim-witted, look-a-like servants, and Voltaire’s buxom, sex-obsessed niece, who fancies herself an ingénue.
