Deep Blue Sea

A group of scientists have a deep-sea research facility called Aquatica. In the facility, they have discovered that there is an enzyme in shark brains that can re-activate human brain cells. They have three sharks: two "small" Gen I Mako's and a massive Gen II Mako, about 25 feet long. They have had to increase the shark's brain mass to get the enzyme, but the sharks are smarter as a side-effect.

Suddenly, during a storm, the sharks cause an accident which sparks off a chain of events which starts to sink Aquatica. The small group of humans then need to find a way out before they are killed.

Revealing mistake: When the shark first attacks and bites off Jim's arm, you can see his real arm under his shirt as he's scrambling away from the water. (00:34:10)

Russell Franklin: You think water moves fast? You should see ice. It moves like it has a mind. Like it knows it killed the world once and got a taste for murder. After the avalanche, it took us a week to climb out. Now, I don't know exactly when we turned on each other, but I know that seven of us survived the slide... And only five made it out. Now we took an oath, that I'm breaking now. We said we'd say it was the snow that killed the other two, but it wasn't. Nature is lethal but it doesn't hold a candle to man.

Question: Was there supposed to be some more of the scene between Carter and Susan after she had killed the third shark?

Answer: I assume you are referring to the scene after Susan killed the second shark (she was killed before the third shark was killed). The comments LL makes to finish that scene do seem a little out of place with what they were talking about but the film does have a number of scenes cut out. Most of the deleted scenes on the DVD deal with character development and dialogue but there is no evidence the scene was cut as the DVD's deleted scenes dont have any extra footage on that scene or alternate dialogue.

Lummie

Answer: Yes, Susan and Carter actually share a kiss in the original ending. They grew smitten with one another in unreleased deleted scenes leading up to it. The kiss is interrupted by Sherman "Preacher" Dudley clearing his throat, who's still recovering from his wounds. This, of course, was part of the unreleased original ending that was changed at the last minute due to test audiences wanting Susan to die. The footage was never released but there are stills from said kiss and this was how it was scripted to end. Fans started a petition on the Change site asking Warner to release the original ending and even Thomas Jane is promoting it on his Instagram account. But as of now, the ending has yet to be released.
