- During the filming process, the crew used more than 50 large and small boats, of which a 145-foot-long barge was used to sink two DC3 aircraft to the bottom of the sea, and some small boats not only had cafeterias, but also equipped with hot water. The bathtub is used to warm up actors who shoot underwater shots.
- Three freighters of the same model were used in the filming. One was sunk in deep water for long-range shooting, one was sunk in shallow water for close-up shooting, and one was used for close-up and interior shooting.
- Out of prudence, Sony has partially treated Jessica Alba wearing an overly revealing bikini in the trailer.
- In order to make the film meet the PG-13 standard, many violent scenes in the film were deleted.
- Paul Walker and Jessica Alba received closed high-intensity boat and diving skills training before shooting.
- The crew hired a large number of locals in the Bahamas, including experienced shark and diving expert Stewart Koff. His employees and boats also participated in the filming.

Jared: Yeah, I know, but I lost my watch.
Bryce: You lost - ? You need an arm to wear a watch. Would you get out of the water, stupid? Please?
Jared: Sam gave me this watch for my birthday.
Bryce: I don't care! Sam, get...
[Sam tosses to Jared his mask and fins]
Bryce: What are you doing?
Sam: He's fine. They're just curious.
Bryce: Oh, curious as to what? As to what? What his ass tastes like?

Jared: Remember I told you, if anything happened to Sam, I was gonna kill you?
Bryce: Oh, don't do that.
[Jared picks up a chair and throws it at the railing]
Bryce: Don't hit me with the fucking chair.
