Outside of ‘Jaws,’ it’s difficult to find good killer shark movies. There are dozens, if not hundreds of B-grade shark films, which makes finding the A-listers a real treat. In my opinion, ‘Deep Blue Sea,’ a 1999 horror/thriller that finds the staff of a research facility fighting for their lives against super-intelligent mako sharks, is one of those treats. While the premise is B-grade material, the high production values, humor, and willingness to embrace its R rating makes this one of Hollywood’s better shark films.

With all that said, let’s take a look and see (haha) what we can learn from this tale of genetic experimentation gone wrong.

1. Consider throwing the standard ‘who’s going to die’ rules out the window

Much like George R. R. Martin’s ‘Game of Thrones’ saga, ‘Deep Blue Sea’ throws the conventional rules for who lives and dies out the window and spares those we thought would die, and spares those we thought would live. Some examples:

The horny young adults in the opening all survive:

 

The most famous actor becomes shark food less than halfway through the film:

 

 

 

All three ladies die (though only one in this clip):

 

 

 

 

And even the cute animal gets eaten!

 

 

 

 

 

The first time I saw the film, I was shocked at how everyone I thought was going to live, died, and was on the edge of my seat wondering who was going to get out alive or not.

In our own stories, defying the conventions of who’s going to die is a fantastic way of getting people’s attention. Instead of having the hyper-sexual, booze drinking teen die first in a slasher movie, have him survive all the way through. Have the intelligent, smart, resourceful character be the first to bite the dust. When your audience realizes that there really is no guarantees on who’s going to live and die, they’ll want to keep going to find out who makes it or not.

2. Consider putting your characters inside an isolated environment that’s failing

Like any good horror film, ‘Deep Blue Sea’ puts its characters inside a location that’s constantly unsafe and makes their escape to safety that much harder. In this instance, it’s a partially-submerged research facility that begins to sink once the chaos begins, letting the sharks swim inside to make escape even more difficult.

The advantage of having your main location falling apart in stages is that the characters never have much time to rest. They always need to stay on the move, with any safe place offering only temporary refuge, which helps keep them – and the audience – on their toes.

3. Consider making someone do the worst thing for the most righteous of reasons

While most shark films have a human villain corrupted by greed, a desire for power, or any other human failing, Dr. Susan McAlester is a refreshing chance of pace: she’s not motivated by greed or selfishness, but from wanting to cure Alzheimers. Considering that she finally has that cure within reach, it’s not surprising that she’s willing to bend the rules of what’s ethically and legally acceptable, but unlike so many other villains, she doesn’t set out to hurt anyone, which makes her the most interesting and multi-faced character of the film.

In our own stories, well-intended extremists, if handled well, can be the most interesting characters because they make us wonder what we’d be willing to do to accomplish a noble goal. Would we be willing to harm others? Would we be willing to break the law? And on top of that, would we be willing to sacrifice lives to accomplish that goal? Or would we still try to avoid hurting others as much as possible? Having seen the devastating effects of Alzheimers myself, I can understand why Susan did what she did, and I imagine many other viewers would feel the same way, which makes her ultimate failure in getting that cure to the surface all the more devastating.

4. Consider making the monsters more intelligent than we initially realize

The sharks of ‘Deep Blue Sea’ demonstrate their intelligence early on by using a stretcher as a weapon to break the underwater window of the main lab on the station, but it isn’t until near the end of the film that we learn that they’ve been secretly herding our protagonists where they want to ensure the station keeps flooding and sinking, so they can break out of the facility and into the open ocean.

In our own stories, gradually revealing a monster’s intelligence is a great way to make the audience realize that whatever our protagonists are messing with is more than just another dumb monster. It’s also a great opportunity for the audience to have an ‘oh crap!’ moment when we realize that the monster has had an ulterior motive all along that we weren’t aware of (but will subsequently catch on rewatches/re-reads).

5. Consider having your comedic relief be a competent fighter

It’s distressingly common for comic relief characters to be bumbling fools who are only good at cracking jokes, shrieking, and being burdens to the main characters. ‘Deep Blue Sea’ bucks that trend by having Preacher, the religious cook, be both amusing and a surprisingly good fighter: he manages to take out two of the three sharks in the film, survives being mauled by a shark (by using his crucifix to stab a shark in the eye), and saves the day by blowing up the last shark despite being badly hurt, thus keeping the sharks from breeding in the wild.

In our own stories, comedic relief characters need not be walking joke machines that everyone else would gladly leave behind: By making them competent (or at least willing to fight instead of trying to run away), and even come to rescue other characters, you can help make them the most likeable characters in your story.

6. Consider having the monster recognize its maker

 

 

What would you do if you came face-to-face with God? Would you shake His/Her/Its hand? Slap His/Her/Its face and scream about how unfair your life has been? In ‘Deep Blue Sea’ we get a moment where the last shark comes face to face with Susan and stops, clearly recognizing her… before chomping her into so many bite-sized pieces.

In our own stories, having a monster meet its maker offers an opportunity to get a glimpse of the monster’s inner workings. While killing its maker is the standard response, consider having the monster be awed, confused, puzzled, intrigued, or even worshipful; this gives us, the author, a chance to have the beast dispatched in a unique way (perhaps by having its maker lure it into a hydraulic press), or by persuading it to stop killing.

The Takeaway:

When doing a monster movie, consider having your characters be trapped in a location that’s failing, and killing off people we expect to see live, and vice versa, while having a competent comedic relief who’s not a burden to others, and having the main human antagonist be a genuinely good person who did something awful for the best possible reasons and create a monster that we come to realize is far smarter than we first imagined, and then having that monster encounter their maker and having it do something other than just treating them like any other victim they’ve met.
