Sartre wrote successfully in a number of literary modes and made major contributions to literary criticism and literary biography. His plays are richly symbolic and serve as a means of conveying his philosophy. The best-known, Huis-clos (No Exit), contains the famous line "L'enfer, c'est les autres", usually translated as "Hell is other people." Aside from the impact of Nausea, Sartre's major work of fiction was The Roads to Freedom trilogy which charts the progression of how World War II affected Sartre's ideas. In this way, Roads to Freedom presents a less theoretical and more practical approach to existentialism.
John Huston got Sartre to script his film Freud: The Secret Passion. However it was too long and Sartre withdrew his name from the film's credits. Nevertheless, many key elements from Sartre's script survive in the finished film.
Despite their similarities as polemicists, novelists, adapters, and playwrights, Sartre's literary work has been counterposed, often pejoratively, to that of Camus in the popular imagination. In 1948 the Roman Catholic Church placed Sartre's oeuvre on the Index Librorum Prohibitorum (List of Prohibited Books).
