To start, it appears that we’re really finally going to get James Cameron’s The Abyss on Blu-ray. Speaking at Comic-Con on a panel celebrating the 30th Anniversary of Aliens, the director revealed of The Abyss: “We’ve done a [new] wet-gate 4K scan of the original negative, and it’s going to look insanely good,” Cameron said. “We’re going to do an authoring pass in the DI for Blu-ray and HDR at the same time.” He confirmed that it’s likely due in 2017, and the fact that an HDR pass is being done too strongly suggests that a 4K Ultra HD Blu-ray version will be released at the same time.
