Justice Potter Stewart wrote in a concurring opinion in Jacobellis v. Ohio (1964): “I shall not today attempt further to define the kinds of material I understand to be embraced within that shorthand description; and perhaps I could never succeed in intelligibly doing so. But I know it when I see it, and the motion picture involved in this case is not that.” The movie in question was a French drama film entitled Les Amants (meaning The Lovers), featuring French actress Jeanne Moreau. The phrase became one of the most well-known and oft-cited phrases in modern Supreme Court history. Stewart later regretted that his phrase became so popular, saying: “I think that’s going to be on my tombstone.”
