DC Comics have been known to play hard ball with comic book creators and exclusives in the past. Famously when CrossGen started signing up creators to work exclusively for them, DC Comics dropped the creators completely when hearing the news. This was even if they were half way into finishing a book. Instead DC would get new creative teams to start the book over from scratch, rather than in any way promote a creator who was heading off elsewhere.
Now it seems that it's working the other way. I hear tell that DC are demanding that creators jump off existing projects immediately when signing up to an exclusive deal, no matter what personal commitments the creator may have made to their current publisher.
And it's a carrot worth taking for many. Not only are there decent employee benefits and the guarantee of regular work, but one creator found his page rate dropped when he recently came out of an exclusive with the publisher.
Naturally Marvel are on the receiving end of a few of these problems – keen viewers may be able to spot a sudden creative change on a Marvel book and draw their own conclusions before DC make an announcement.
Because it seems like this summer is going to be full of them!
