Oh, I just double checked and you're right. I could sworn I saw his named listed under the executive producers. Technically it was a Vertigo comic, and as far as I know the comics took place in their own world with no connections to the DCU. So that's probably the show wasn't part of the Arrowverse. I'm pretty sure they would have listed him with the other producers in the article if he was involved. Constantine and Lucifer both took place in the DCU, but I, Zombie did not. Well technically, the Lucifer comics are spun off from a DCU comic, I'm not sure if they ever had any DCU connections in the Lucifer comic.
