Here's a bit from the blog:
"By the time I got back [from travel to France], the project was dead. By 'dead,' I mean that it won’t be happening. I don’t think it’s on the studio’s radar at all. It may come back in another incarnation, with another writer, but I can say with considerable certainty that it won’t be the version I developed."
"Yes, that sucks. And obviously, I can only share my interpretation of what transpired. There were dozens of meetings and phone calls in which I had no participation. As a reader, you should certainly consider the possibility that I wrote shitty scripts they simply didn’t want to make. Because Warners controls copyright on them, I can’t put them in the Library for you to read yourself. So you have to decide whether to take my word on it."
