Other sources have discussed the story in varying degrees of detail, including a section in Diderot's Encyclopédie, in the "Histoire du Parlement de Paris" by Voltaire and in a number of books written in the nineteenth century, including a work in the 1880s by a descendant of Jacques Le Gris in which the author attempted to prove his ancestor's innocence. In the twentieth century other authors have studied the case, the most recent being "" in 2004, by Eric Jager, a professor of English at UCLA.. Ridley Scott is adapting Jager's book into a film, "The Last Duel", starring Matt Damon as de Carrouges.
