XIII came to life as a graphic novel series by the Belgian writing/drawing duo of Jean Van Hamme and William Vance. The property is known to a handful of Americans because it was adapted into a first-person shooter video game in 2003. Few who played that cult-fave had any idea of the story’s illustrated origins, however. In 2008, a French-Canadian miniseries (XIII: The Conspiracy starring Stephen Dorff and Val Kilmer) adapted Van Hamme and Vance’s original storyline. That proved successful enough—in Europe, anyway—to inspire a spin-off series in 2011.
