The TV business is harsh and unforgiving. Even when all the steps are taken to get a show made, they often fail and find themselves canceled…sometimes before even getting a fair enough shot to grow their fanbase. And when a show does fail, most of the blame falls on the showrunner. Even when shows are a smashing success, such as AMC’s The Walking Dead, the job of showrunner can prove to be a daunting task.

A new documentary titled Showrunners: The Art of Running a TV Show is on the way, and aims to shine a light on one of the more challenging jobs in the entertainment industry. In it, a veritable who’s who of top TV showrunners talk about their work, including J.J. Abrams, Joss Whedon, Damon Lindelof, Terence Winter, Ronald D. Moore, and many more.

A trailer for the documentary has been released, and you can check it out below.
