Tijdens de TCA dit weekeinde kwamen de makers en de cast langs om te vertellen over iZombie aan wie we nu de term ZILF hebben te danken. De website Collider was hier ook aanwezig en heeft in dit artikel alle feiten voor je op een rij gezet en daar van kan je hier onder een stukje lezen.

The show will diverge significantly from the comic book source material. Thomas explained, "In the iZombie comic book, there's a whole monster universe. There are were-terriers and ghosts. We wanted to stay strictly zombie, so we only have zombies in the show. And we really needed a story engine. We wanted to do a case-of-the-week show. In the comic book, the main character is a gravedigger and that's how she gets her brains. By making her an assistant medical examiner and putting her in the morgue, it gave us our case of the week that we wanted."

When Liv eats a brain she inherits not only memories and dreams, but skills and talents from the person who it belonged to. According to Thomas, "One of the big elements that we did retain from the comic book is the idea that when she eats brains, she gets the memories of the dead people. That was one of the big selling points in the comic book. And then, when we started getting into the writers' room and talking about whether she's going to inherit the talents of the people that she ate, there were lively and lengthy discussions about how far do we go with that."
