Shout! Factory has announced the upcoming release on August 6 of the acclaimed documentary feature What We Left Behind: Looking Back at Star Trek: Deep Space Nine (DVD: $16.99, Blu-ray: 2 discs, $22.99). An in-depth look at the past, present, and future of a series whose dark, edgy take on Gene Roddenberry’s vision was often misunderstood when it premiered but has grown into a beloved mainstay in the Star Trek franchise, directors Ira Steven Behr and David Zappone’s film features extensive new interviews with the cast and crew of Deep Space Nine as well as newly remastered HD footage from the TV series. The film also focuses on the original writers of the series as they craft a brand-new episode of Star Trek: Deep Space Nine, developing what would be the eighth-season premiere if the show were to return to the air today. Bonus features include deleted scenes, behind-the-scenes featurettes, and a segment on the HD restoration process. The special edition Blu-ray includes an exclusive reunion with composers Dennis McCarthy and Kevin Kiner, as well as a 50-minute roundtable discussion with the crew.
