James Erwin

As an author Erwin's first book, a historical encyclopedia about secessionist movements in the United States titled Declarations of Independence, was published in 2007. He worked as a technical writer. He wrote a second historical encyclopedia in 2010 but it was never published due to the sale of the publisher, Facts on File. FT, Popular Mechanics, and other media.

In 2013, it was revealed that Apollo 18 screenwriter Brian Miller had been hired by Warner Brothers to write a second draft of the screenplay. By 2018, the screenplay had been languishing in development hell for five years since the most recent script rewrite of 2013 and has yet to be picked up for further development.

Erwin parlayed his success into a Kickstarter campaign for his first novel Acadia.
