Lang's most seminal film was M (1931, Germ.) - his first sound feature (bridging the gap between silents and talkies). It was an expressionistic psychological thriller about a child molester serial killer. The pedophile-psychopath was identified as Hans Beckert (Peter Lorre) - his coat back was marked in chalk with the letter "M." He was caught hiding in an attic, and taken to a large abandoned brewery building to stand trial, where he was questioned by a panel of underworld boss-leaders.
Because French forces suffered disastrous defeats and a series of defections at the onset of the war, Robespierre and Danton feared the possibility of a military coup d'état ,  above all one led by the Marquis de Lafayette , who in June advocated the suppression of the Jacobin Club. Robespierre publicly attacked him in scathing terms: "General, while from the midst of your camp you declared war upon me, which you had thus far spared for the enemies of our state, while you denounced me as an enemy of liberty to the army, national guard and Nation in letters published by your purchased papers, I had thought myself only disputing with a general... but not yet the dictator of France, arbitrator of the state." 
Centered on the dialogues and publications of the French “philosophes” (Voltaire, Rousseau, Montesquieu, Buffon and Diderot), the High Enlightenment might best be summed up by one historian’s summary of Voltaire’s “Philosophical Dictionary”: “a chaos of clear ideas.” Foremost among these was the notion that everything in the universe could be rationally demystified and cataloged. The signature publication of the period was Diderot’s “Encyclopédie” (1751-77), which brought together leading authors to produce an ambitious compilation of human knowledge.
