Web series Universal Dead recently announced that it is becoming a feature film, and has just released another installment. In episode 3, Doug Jones (Hellboy) explores the zombie problem that he and CDC representative Gary Graham disagree on. Episode 3 asks the unanswered question, "Do zombies shit?" It also raises a correlation between zombies and other members of the undead. (we highly recommend watching Episode 1 and Episode 2 before watching Episode 3.
The popular webseries is written by Kelly Parks and directed by Vernon Mortenson. And yes, that was D.B. Sweeney.
