The new issue of Scary Monsters. (#99) features a pretty good interview with Christopher Pennock. He discusses his DS time in depth, even sharing the names of some of the other actors who auditioned for Jeb: Jon Voight, Christopher Walken, Tommy Lee Jones and Christopher Bernau. It's an interesting piece from the viewpoint of someone who came in on the tale end of the hardcore DS mania and was there for the final year.
And, as a bonus, the magazine also features a photo of longtime DS fan Guy Haines.
