Grant Morrison in Comic Foundry

Because it's worth repeating:

Comic Foundry: You’ve done several big event books for DC. What’s the hardest part about writing them?

Grant Morrison: Trying not to disturb continuity too much, particularly in cases where said continuity is best described as a car wreck. Back in 2006, I requested a moratorium on the New Gods so that I could build up some foreboding and create anticipation for their return in a new form … instead, the characters were passed around like hepatitis B to practically every writer at DC to toy with as they pleased, which, to be honest, makes it very difficult for me to reintroduce them with any sense of novelty, mystery or grandeur. So in cases like this, where fellow creators have overlooked my carefully established additions to DC continuity or ignored my pleas to hold certain characters in reserve, my intention is to follow the through-line I’ve established in my own work so that there’s at least some long-term consistency.
