A 20-minute retrospective is titled Remembering it Came from Beneath the Sea. Some information is redundant as it also is stated within the commentary track on the feature. Six photo galleries follow. A Modern Look at Stop Motion features a student discussing the process as it stands today. The rest of these extras are pulled from the 20 Million disc.
Tim Burton Sits with Ray Harryhausen is an extended face-to-face meeting between the two men. Their chat is informative and fun, and even includes some showcasing of props from Earth vs. the Flying Saucers. It runs quite long at 27 minutes. Film Music's Unsung Hero is a retrospective hosted by David Schechter. This is another long one, looking at the stock or only slightly altered stock tracks crafted by Mischa Bakaleinikoff. His familiar themes would be used in countless films.
An 18-minute featurette looks at advertising from the era, from lobby cards to detailed press kits. A digital comic is presented as a sequel to the film and wraps up the extras. It is filled with solid art, though it's a shame the physical version wasn't included in the case. Finally, BD-Live connectivity is on the disc, but it’s only a link to download trailers. 
It Came from Beneath the Sea is sadly only available in a box set on Blu-ray, and not as a stand alone release. It’s a cheap move as many fans probably already purchased 20 Million Miles to Earth separately when it was released last year.
