From Paul: I asked our award winning adaptor Robert  Kauzlaric to contribute some insight into his process for this blog.  
There’s so  much to discuss about this project, and Paul and Maren have already done an  amazing job of that here. As the adaptor of the show, there are load  of things on my mind I’m hoping to blather about on this blog, in particular: the rewards and  challenges of working with such well-known and well-loved material –  what do you cut? what do you keep? how do you stay true to the story  while transposing it to a new medium with an entirely different set of  restrictions/challenges/etc.  But before I attempt to open that can of  discussion-worms, I thought it might be appropriate to share a little  background on how I arrived at this point.
It was over 10 years ago that a  friend first handed me a  copy of Neverwhere  with an off-hand, “This seems like it’d be right up your alley.” Indeed  it was. I devoured it in a couple of days. Then I read it again. I had  to put it away for a while out of necessity, but it kept churning in the back of my mind for months. I couldn’t  get the insane notion out of my head that it would make for an amazing  piece of theater… I just  couldn’t figure out what company would be willing to tackle it, much  less let me adapt it for them.
Then, in early 2000, I saw Lifeline’s  production of The Two Towers (the first MainStage show I ever saw here) and knew I’d found a place that would be insane  enough to do it. And that they’d do it right: with  love and respect for the source; with love and respect of the audience;  with heart, humor, danger, and passion.  Later  that year, I was cast in The Silver Chair, and I got my first exposure to the Lifeline process, from an  early reading of the script, through auditions, rehearsals, tech, and  production… and I knew it was exactly the kind of  process in which I would like to see it develop. 
So, without any reason to suspect  that my secret plan (known only to me) to have my hypothetical  adaptation of Neverwhere get produced at Lifeline would, in a million years, actually, possibly, maybe, ever  happen… I got right to work on my script.  I had  no idea if rights were available. I had no serious hope that anyone  would actually produce it. But that didn’t really matter to me. I was feeling wildly optimistic. Not even a beating from Mr. Vandemar could have stopped me.
I finished my first draft and sent  it off to some close friends who were willing to give me feedback and  help me wrap my head around what I’d gotten myself into. Several months  later, draft two was read aloud by a circle of friends, and I got more  valuable feedback. Rinse and repeat with draft three. I’m so indebted to  those friends of nearly a decade ago (circa 2001)  who helped to nurture this project even when it  didn’t have a hope of ever getting produced (except in my mind). Some of those friends have since moved away from Chicago, but their influence is still  felt by me every time I pore through the script.  (Thanks to Chris, John, Dan, Gail, Cath, Tom, Matt, Mark, Mark, Elise,  and everyone I’m forgetting.)
Then I sent the script around to some director friends, and  some companies I had closer relationships with at the time. The feedback  was positive, but I heard a lot of, “This is cool, but seems a bit  impossible. Good luck getting it produced!” Heartache ensued. The script  idled on my computer as I turned my attention to other projects for a while.
In 2002, I attended  one of Mr. Gaiman’s readings on the American  Gods tour and was blown away by the sheer  awesomeness of the experience (if you haven’t seen him read his own work  yet, DO SO). I got my book signed, shook his hand, chatted with him  ever-so-briefly, and wondered if my dream of adapting Neverwhere would ever happen.
In 2003, nursing a broken leg, I  finally found DVD copies of the original BBC miniseries and devoured all  six hours and all of the commentary. Trapped on my sofa with a full leg  cast and my cats for company, I lost myself in London Below once more  and began, admittedly, to mourn my dream of adapting the piece for the stage. The possibility seemed such an unattainable long-shot at that  point. Perhaps the painkillers were making me excessively maudlin, but I  started to fear my secret little dream would never be realized.
But by early 2005, I had appeared in six productions at Lifeline,  and had finally established  an actual ongoing relationship with the ensemble.  The time was right to formally submit the script to the theatre. My  hopes were high. I got feedback from more friends  about the script. I re-edited the script. I sent off the script. And waited. 
And waited. 
Finally, as it  turns out, the rights weren’t available. And, in  any event, the timing wasn’t right for the ensemble to get behind it. The company only knew me as  an actor. I hadn’t made a  strong enough push to establish myself as a writer in their eyes. Nor (in retrospect), had I truly  attempted to convey the full extend of my excitement about the project  to them. I was hugely disappointed at the time,  but I get it now. 
Later  that year, I was honored to be asked to join the company and got my first direct exposure to the  script-selection process from the “inside.” About a year  later, I got my first writing opportunity with the company: a KidSeries  musical adaptation of The True Story  of the 3 Little Pigs! Time passed. Paul  and I tackled The Island of Dr. Moreau. I dove into the world of Oscar Wilde with The Picture of Dorian Gray. And by mid-2008 or so (if I have my  timing correct), I re-introduced the company to my  Neverwhere idea and  by this time there was interest, trust and solid support. And in Paul, I  had the perfect director-partner committed to seeing the project  through with me. All we needed was to get the rights. 
And then last  year, they came through. 
And there was celebration.
So, in January of 2009, nearly 10  years after I first started working on my script, I dove back in. We  held a reading with the ensemble and with their invaluable feedback, a  brand new draft emerged. This past summer, we cast the show. In early  December, we held another reading with the cast and ensemble, and brought the production team in on the discussions. Again, everyone’s  insights were invaluable.  And Paul and I met repeatedly for a month to discuss character,  direction, tone, theme, style and all that other great theatre-type  stuff. 
Now, here I sit  in February of 2010, a mere two weeks away from the beginning of the  rehearsal process. We’ve got an amazing cast and design team, all geeked  to the gills about working on such wonderful source material. The long,  SOLITARY portion of my journey is over as the project now gets placed  in the capable hands of a massive TEAM of people, all working to tell  the story, hone the production, and realize the theatrical vision of the  piece. 
And I, for one,  couldn’t be more excited to see how it all turns out.
