History Trivia / DeepBlueSea

* AllStarCast: The cast includes familiar faces like Creator/ThomasJane, Saffron Burrows, Creator/SamuelLJackson, Music/LLCoolJ, and Creator/StellanSkarsgard.

** There was cut footage that made clear that the relationship between Dr. Whitlock and Janice was not only sexual, but that she was pregnant with his child. This was cut on the basis that it would have made Janice's death "not feel right", according to director Renny Harlin.

** Samuel L. Jackson improvised the ''Series/FantasyIsland'' joke.
* VacationDearBoy: In the commentary track, both director and Creator/SamuelLJackson admit that the only reason the actor agreed to be in the movie was he got to golf between his takes (although Jackson also admitted he liked the prospect of [[Film/TheLongKissGoodnight reuniting]] with Creator/RennyHarlin and [[AwesomeDearBoy being in a monster movie similar to ones he grew up watching]]).

* ExecutiveMeddling: The film was originally set to end with [[https://lostmediawiki.com/Deep_Blue_Sea_(lost_original_ending_of_sci-fi_horror_film;_1999) Susan not only surviving, but delivering the fatal blow to the shark]], before embracing Carter. However, during test screenings of the film, audience members were so incensed at Susan, who orchestrated the whole disaster and was unlikeable to boot, that they repeatedly yelled "Die, Bitch!" during the final act. As a result, the ending was reshot to have Susan perform a HeroicSacrifice to stop the shark from escaping the perimeter fence, while her role was slightly toned down and Preacher's (Creator/LLCoolJ) was beefed up to make him more of a heroic character.

* ActorInspiredElement: Creator/SamuelLJackson came up with his character's [[https://beforesandafters.com/2019/07/24/deep-blue-sea-samuel-l-jackson-sharks-death/ sudden death scene.]] Originally, he was given a lengthy speech, but both he and the FX team thought that the dialogue was absolutely terrible, so he asked them "you know, why don't you just kill me?" And thus was born one of the film's most famous scenes.

** There was cut footage that made the relationship between Dr. Whitlock and Janice was not only sexual, but that she was pregnant with his child. This was cut on the basis that it would have made the character's death "not feel right", according to director Renny Harlin.

* DeletedRole: Creator/RonnyCox shows up ''very'' briefly as the company partner and co-CEO of Russell Franklin in the beginning, where he doesn't even say anything. Presumably the footage was cut.

* ExecutiveMeddling: Originally, [[spoiler: Dr. Susan was to survive and Preacher would be sharked.]] Test audiences found [[spoiler: Susan]] to be such an [[TheScrappy irritating twerp]] that this was inverted. [[RuleOfCool Makes for a damn fine climax]].

* VacationDearBoy: In the commentary track, both director and Creator/SamuelLJackson admit that the only reason the actor agreed to be in the movie was he got to golf between his takes. (although Jackson also admitted he liked the prospect of [[Film/TheLongKissGoodnight reuniting]] with Renny Harlin and [[AwesomeDearBoy being in a monster movie similar to ones he grew up watching]])

* ThrowItIn: A somewhat dark example: the scene where everyone is running away from the water after the lab window breaks ''actually happened'': the tank broke and the actors had to suddenly run away from three tons of water. [[EnforcedMethodActing The terror in their faces as they run for their lives is real]]. Renny Harlin decided to keep the footage in.

* DeletedRole: Creator/RonnyCox shows up ''very'' briefly as the company CEO in the beginning, where he doesn't even say anything. Presumably the footage was cut.

** [[Series/TheSopranos Tony's sister Janice]] is handling the communications at the research station.

* ShoutOut: To ''Film/{{Jaws}}'', of course. It opens with the shark's POV, the scene where Susan confronts a shark in the lab is similar to the one with Brody inside the sinking Orca, and [[spoiler:two of the sharks are blown (like in the original) and one is electrocuted (like in ''Film/{{Jaws 2}}'').]]
** Even the way the sharks attack is reminiscent of several Jaws movies. As an example, how the shark tears off the arm of one of the scientists is from ''Film/JawsTheRevenge'', and when the shark crashes against the window is from ''Film/Jaws3D''.
** Preacher's hiding in the oven looks a lot like a similar scene in ''Franchise/JurassicPark''.
** The scene of the vertical-shaft climb is a clear homage to ''ThePoseidonAdventure''.

* ExecutiveMeddling: Mixed with what can be called viewer meddling. [[spoiler:In the original version of the movie which was shown to a test audience, Preacher was killed by the sharks, while Dr. Susan survived as the love interest to Carter. However because of her actions during the movie and being pretty much the cause of all the deaths, the audience had begun to hate her, disliking the ending for this. The producers took their opinion seriously and changed the movie to Susan being killed gruesomely, while Preacher survives.]]
** [[spoiler:Susan's death also counts as RedemptionEqualsDeath.]]
** If you think about it, this turns the movie's ending from [[spoiler:BittersweetEnding to a DownerEnding: since she died, all hopes of salvaging the Alzheimer's research were lost and thus all those people died in vain.]]
*** [[spoiler:At least until you [[FridgeLogic realize]] that the fact that survivors know the experiment worked is enough information for someone else to do it again.]]
