A case of no movie can match the budget of your own mind.
I saw some of the concept art that Celtic Rose turned out and I'm forced to say it was really good. They had the feel about right. There was an AMAZING image of Deadboy.
We'll see, there has been one approach about the rights so far (which I can say nothing about, sorry).
As to how much involvement Simon would have, well, that's down to the contract and what the buyer wants to do.
When there was an approach for the Hawk and Fisher rights a few years ago they wanted to fly Simon to LA an co-write the script (this was for one of the big studio's). But then they changed their minds!
In the end, if someone's was to wave a cheque with telephone numbers written across it would you turn it down?
Hey there Steve, I just joined this website 30 minutes ago, I know it is possible that there might never be a Darkside TV series since the fan base has become silent and seems like no one is taking the contract(? however since celtic rose lost the movie contract, is it possible you can show us some concept art they made that you speak of? It' s rather strange, been reading nightside again and again for 5 years now, yet I still wonder, what it could have become. Hope to hear from you soon!
