Synopsis: Action/thriller about genetically enhanced supersharks wreaking havoc in an underwater research lab. As the sharks go crazy, the main characters try to worm their way to the top of the underwater facility, which is coming apart at the seams and letting in great amounts of water.
From the Frying Pan into the Studio Tanks (HD; 25:08) is a really appealing new interview with production designer William Sandell, whose name may frankly not be all that well known, but who has some impressive credits in addition to this film.
Beneath the Surface (HD; 19:30) is a new visual essay by Trace Thurman which makes the case that the real villain of this film is not the "smart sharks".
When Sharks Attack (HD*; 15:07) is an archival making of featurette.
The Sharks of Deep Blue Sea (HD*; 8:19) is an archival piece looking at the animatronic killers.
Deleted Scenes (HD; 8:02) have optional commentary by Renny Harlin. These are HD in name only and were obviously sourced from a low res source.
