I thought to myself, ‘This is a potentially once in a lifetime kind of opportunity; I don’t think we’re ever going to do a crossover of this scale and ambition again.
It came pretty early on in the process.
I thought that having a comic book tie into [Crisis] would not only be a cool thing to do, it would allow us access to all of the characters that we don’t have in the crossover proper for logistical reasons, or financial reasons, or creative reasons.
