During the shooting of Star Trek, bits and pieces of episodic footage were left on the cutting room floor and later preserved in film canisters by The Roddenberry Estate. Recognizing the value of the footage, CBS painstakingly catalogued, transferred, analyzed, and pieced together these Vault materials, which include alternate takes, deleted scenes, omitted dialogue, outtakes, and original visual FX elements. Star Trek: The Original Series - The Roddenberry Vault includes twelve classic episodes chosen for their relevance to the Vault materials, and presented in 1080p High Definition with both DTS 7.1 Master Audio as well as newly restored original Mono. Eleven of these episodes contain isolated music tracks. Newly recorded audio commentaries appear on three fan-favorite episodes. Each of the set's three discs features documentaries that weave together the previously unseen Vault materials with all-new interviews by key creative and production personnel and famous fans. The three new documentaries exploring the "making of" the celebrated series and its enduring legacy are: Inside The Roddenberry Vault Rod Roddenberry introduces viewers to the discovery of his father's long-lost Star Trek film reels.
