I've written a comprehensive guide for beginning filmmakers, a project that began as pages and pages of notes for my own journey as I learned the how-to's in the entertainment industry. Of course, it helped that I have a Theatre degree (from UCSD) and I've worked as an entertainment attorney.
My second guide is in the works, a more advanced filmmaking how-to. More from the legal side.
I'm also working on a series of fiction books: dark comedy murder mysteries. As they say, "Coming soon!"
