Question: I saw on here that Susan did more than just enhance the sharks brain; my question is why? I know the whole purpose of making their brains larger was so that they could harvest more protein, so why did she have to do more than that?; E.g., make them larger etc.? Added to that, if they really wanted more protein then why not just get more sharks? They only had like three at the time, so could they have gotten more, or were they just for practice? Also, why did they use only Mako sharks? Was there something wrong with any other breed, like Great Whites for instance? I'm talking movie-wise, not filmmaking-wise.
Question: Two questions involving Russel Franklin; Firstly, what was he referencing when he first arrived at Aquatica? It was just before he had the line "I am getting too old" or something to that effect. Second, why does everyone hate him exactly? I can kind if understand the Preacher when he joked saying that Russell was stupid for climbing the mountain, even if it was a joke, but what about everyone else?
Question: What did Janice mean when she called the sharks "one second generation, and two first generation female", or something along those lines?
Question: Were the sharks in this movie animated? It shows the whole shark without showing a machine controlling it.
Question: How could the shark see Samuel Jackson just before it killed him? It wouldn't be able to smell him because he had no blood on him plus he wasn't in the water.
Russell Franklin: Just what the hell did you do to those sharks?
Dr. Susan McCallister: Their brains weren't large enough to harvest sufficient amounts of the protein complex. So we violated the Harvard Compact. Jim and I used gene therapies to increase their brain mass, a larger brain means more protein. As a side effect the sharks got smarter.
Janice Higgins: You stupid bitch!
Trivia: In both Jaws and Deep Blue Sea there is a scene involving a license plate. In Jaws it is removed from the belly of the dead tiger shark. In Deep Blue Sea it is removed from the teeth of a tiger shark. Not only are both sharks the same but both plates are from Louisiana. The license plate number is the same in both films: 007 o 981 Exp 72-73.
