He may not have created Superman, Batman or even the recently deceased Captain America, but as director Andrew D. Cooke illustrates in his informative and compelling documentary, nobody had a greater influence over the development of comic book storytelling than Will Eisner. Both writer and artist, Eisner developed the comic strip and comic book forms into a combination of art and literature, stretching the boundaries of storytelling with a medium that had previously focused on good-versus-evil superhero tales. Eisner was also a producer; he made innovations on the more than half-century-old tradition of comic book production, while always looking for new ways to use the medium for different and more serious types of stories. As a major inspiration to titans of the form-Jules Feiffer, Art Spiegelman, Frank Miller and Max Allan Collins- Eisner had a huge influence on the development of the tremendously popular graphic novel, and the film adaptations of "Sin City," "The Road to Perdition" and "300." Cooke uses footage, as well as interviews with some of those who have followed in Eisner's wake, to explore the broad reach of his influence. The film also features interview footage with Eisner himself, all the more potent since this captivating man passed away in 2005. Cooke provides us with a record of one of the most important creative men in the history of the 20th century-a man who took one of the few American-born art forms and planted the seeds that allowed it to blossom, beyond even his wildest dreams.
