Star Trek: Deep Space Nine has often been regarded as the outlier of the Trek family of shows, a series that did things differently. It never had the same level of mainstream success as its predecessor, The Next Generation, and yet it has grown over the years to be regarded by many fans as perhaps the best of the Star Trek shows.
And now, a new documentary about the history of Deep Space Nine is heading to theaters. What We Left Behind: Looking Back at Star Trek: Deep Space Nine will be released by Fathom Events in more than 800 movie theaters in the U.S. on Monday, May 13. And IGN has the exclusive debut of the film’s trailer — watch it above!
