People keep asking about whether or not there will be future installments of Femme Noir and Perils On Planet X. The short answer: there's nothing planned.
Joe Staton and I did have a Femme Noir miniseries in the works, and had it pretty much ready to go. We even thought we had a major publisher lined up... but it fell through. Other publishers were approached and seemed mildly interested, but offered no commitments. With Joe's Dick Tracy workload, it's not practical to produce a four-issue miniseries on spec, so....
As for Perils On Planet X, we simply haven't sold enough copies of the first miniseries for Gene Gonzales and I to feel that a second would be worth our while. I'm still trying to get the existing issues on Comixology and may put together a trade paperback collection, so if there's a spike in interest/sales it's not impossible that we'll get to produce Volumes 2 and 3, but it's not very likely.
So, what is in the works?
There will be a new Gravedigger miniseries, "The Abductors," most likely in late 2017 from Action Lab comics. Rick Burchett and I also have plans for a very different comics project - a sci-fi adventure epic - once Gravedigger Vol. 2 is finished.
I'm still working on the Space Crusaders graphic novel with Peter Grau, though I have no idea when it will be finished... and that's all I have cooking at the moment, comics-wise.
I have a couple other projects percolating, but they're in the earliest stages, and I'm waiting on some collaborators to find time in their schedules.
So, there we go. I've got some scripts to finish up that should keep me busy through the end of the year, but not much planned for next year.
Hopefully, I'll find some artists that want to team up with me on some new stuff... I've got lots of stories left to tell.
