Justice League International, Kraven’s Last Hunt, Moonshadow, Spider-Man: The Clone Saga, Dr. Fate, all classics that find themselves in the resumé of a master of the craft: J.M. DeMatteis, an industry legend that has either created, conceptualized, collaborated, or led the creative collective behind the comics mentioned above.
This year’s San Diego Comic Con 2025 saw a Spotlight panel dedicated to DeMatteis’s life and work, and well earned one at that. These types of panels often go down the route of origin stories, little known anecdotes, and key bits of industry knowledge that speak to the figure’s place in the overall trajectory of the medium’s history.
While DeMatteis ticked all these boxes, what truly stood out from the one-hour panel were the notes he gave on the creative process. After the author’s origin story was laid out, the rest of the panel felt like an in-depth class on creativity and execution.
