Born and raised in Brooklyn, New York, J. M. DeMatteis was a professional musician and rock music journalist before entering the comic book field. DeMatteis has written almost all of the major DC and Marvel iconsincluding memorable runs on Spider-Man (his classic "Kraven's Last Hunt" was voted as the number one Spider-Man story of all time in a 2012 Comic Book Resources poll) and Justice League (winning DeMatteis and his collaborators, Keith Giffen and Kevin Maguire, comics highest honor, the Eisner Award); but his greatest acclaim has come for sophisticated original graphic novels like Seekers Into The Mystery, Blood: A Tale, The Last One, and Mercy. The autobiographical Brooklyn Dreams was picked by the ALA as one of the Ten Best Graphic Novels and Booklist, in a starred review, called it as graphically distinguished and creatively novelistic a graphic novel as has ever been...a classic of the form. The groundbreaking Moonshadow was chosen (along with Brooklyn Dreams, Blood and other DeMatteis works) for inclusion in Gene Kanenberg, Jr's 2008 book 500 Essential Graphic Novelswhere it was hailed as one of the finest fantasy graphic novels ever created.
His success in the comic book medium has led DeMatteis to work in both television (writing live action and animation) and movies (creating screenplays for Fox, Disney Feature Animation, directors Carlo Carlei and Chris Columbus and producer Dean Devlin, among others).
In the past decade, DeMatteis has had great success with the acclaimed children's fantasy Abadazadwhich Entertainment Weekly hailed as ...one of those very rare fantasy works that can enchant preteen kids and 40-year old fanboys... and Publisher's Weekly, in a starred review, called an appealing blend of Spirited Away and The Wizard of Oz. Abadazad began life as a CrossGen comic book before morphing into a three-book series published by Disney's Hyperion Books For Children. DeMatteis's 2009 graphic novel, The Life and Times of Savior 28, was called one of the finest superhero stories of the decade by Newsarama.
Recent projects include the fantasy novel Imaginalis, published by Harper Collins, DC's Justice League Dark and Phantom Stranger and episodes of the animated series Batman: The Brave and the Bold and Teen Titans Go. Current projects include DC's Justice League 3001, IDW's The Further Adventures of Augusta Wind, the animated feature Batman: Bad Blood for Warner Home Video (the sequel to last year's Batman vs. Robin), multiple episodes of Cartoon Network's Be Cool, Scooby Doo and a television pilot for Dean Devlin's Electric Entertainment.
DeMatteis continues to teach Imagination 101, a three-day workshop exploring the practicalities and metaphysics of writing for comics, graphic novels and animation. He's also the co-founder of Creation Point, a story consultation service that offers in-depth guidance for both the professional and aspiring writer.
