Originally published in French as Huis Clos (meaning In Camera or "behind closed doors"). English translations have also been performed under the titles 'In Camera', 'No Way Out', and 'Dead End'.
The play features only four characters (one of whom, the Valet, appears for only a very limited time), and one set. No Exit is the source of perhaps Sartre's most famous quotation, "Hell is other people." (In French, "l'enfer, c'est les autres").
