Sartre eventually denounced communism

Camus and Sartre had a public falling out over communism

The two were close friends, sometimes collaborating throughout the 1940s, but the release of Camus' 1951 book, "The Rebel," led to a schism over differing views on communism.

Camus was once a communist, but eventually disavowed the ideology

The writer belonged to the French Communist Party and the Algerian Communist Party in the mid-1930s, but he was eventually expelled for refusing to downplay objections to French colonialism. By the time he published "The Rebel," he was vocally anti-communist, believing it was a utopian ideology that often relied on violence.

Sartre panned 'Citizen Kane'

Jean-Paul Sartre was primarily known for his philosophy, fiction, and drama, but he was also a critic.

Therefore 'Citizen Kane' is not cinema."

See the list of alleged communists Orwell gave to the British government

In 1949, Orwell provided a list of communist sympathizers to a British anti-communist propaganda unit, naming figures like actor Charlie Chaplin and writer John Steinbeck.

Sartre believed those who deny their own freedom are operating in 'bad faith'

Sartre was an elaborate prankster as a student

A mescaline-induced hallucination stayed with Jean-Paul Sartre throughout his life

In 1935, Sartre was injected with mescaline, a psychedelic drug that was then used to treat alcoholism and depression, by his friend at the Hôpital Sainte-Anne in Paris.

For the rest of his life, crustaceans like the ones he saw during the hallucination appeared in his works.

One of Sartre and de Beauvoir's lovers accused them of exploitation

Voltaire's writing sent him into exile

In 1717, the writer's satirical poem "La Henriade" landed him in prison for a year. By 1726, the French government's distaste for his work caused him to leave the country for England, though he returned a few years later. That would be short-lived: In 1734, his "Lettres Philosophiques" sent him packing again, moving to Champagne, then Berlin, then Switzerland, before finally returning to Paris in 1778.
