How To Write a Bone-Chilling Ending To Horror Screenplays

The Final Moments in Horror Are the Most Important

The climax of your horror story is the moment your audience has been holding their breath for—the culmination of every scare, every buildup of tension, and every choice your characters have made, since the opening scene

It’s the scene that will linger in their minds long after the credits roll, the moment that defines whether your film becomes unforgettable or fades into obscurity.

Your final act is your opportunity to tie everything together: the fears you’ve teased, the conflicts you’ve built, and the characters your audience has rooted for (or against). Whether your story ends in tragedy, triumph, or mystery, the climax must deliver on the promises made throughout your script.

So, how do you craft a final act that leaves your audience satisfied but shaken? Here’s how to make your story’s ending unforgettable.


Why Your Final Act Matters

In horror, the ending is your story’s lasting impression. A weak climax can make even the most gripping narrative feel hollow, while a powerful ending ensures your film will haunt audiences long after the lights come on.

The best climaxes in horror are:

  • Terrifying: They escalate the stakes to a point of no return.
  • Emotionally Satisfying: They resolve character arcs and conflicts.
  • Unforgettable: They leave a visual or emotional impression that sticks with the audience.

Whether it’s a shocking twist, a triumphant moment of survival, or a haunting final scare, your ending should deliver the emotional and visceral payoff your audience craves.


5 Pro Tips for Crafting the Perfect Horror Ending

Here are five tips to create a terrifying, emotionally resonant climax:


1. Bring the Story Full Circle

A great ending ties the story’s threads together, creating a sense of completeness and rewarding the audience’s attention. Callbacks to earlier scares, clues, or unresolved moments can create an “aha!” moment that leaves viewers satisfied.

Example:

  • In The Sixth Sense, the shocking revelation about the protagonist recontextualizes the entire film, making the audience see everything in a new light.

 

Pro Tip: Revisit a fear or detail from earlier in the story, giving it new significance in the climax.

2. Escalate the Stakes

Your final act should feel bigger, scarier, and more intense than anything that came before it. This is the moment to push your characters—and your audience—to the edge.

Example:

  • In The Conjuring, the climax reaches its peak as the mother becomes fully possessed, forcing the family and investigators to risk everything in a desperate attempt to save her.

 

Pro Tip: Ask yourself: What’s the ultimate challenge for my characters? 


3. Force the Protagonist to Face Their Fears

Horror climaxes aren’t just about external conflict—they’re about internal resolution. Make your protagonist confront their greatest fear or flaw, creating a moment that resolves their character arc.

Example:

  • In Get Out, Chris overcomes his hesitation and takes action, confronting his captors in a climactic act of empowerment and survival.

 

Pro Tip: Tie the external horror to the protagonist’s internal journey, making the climax as much about emotional growth as it is about survival.


4. Deliver an Unforgettable Visual or Emotional Moment

Your audience should leave your story with one clear, haunting image or feeling. Whether it’s the terrifying reveal of a monster, a moment of eerie silence, or a shocking twist, the final scene should resonate long after it’s over.

Example:

  • In Hereditary, the surreal, disturbing visuals of the climax cement the film’s reputation as a masterpiece of psychological horror.

 

Pro Tip: Choose a single moment, dialogue, or visual to serve as the “punctuation mark” of your story.


5. Leave Room for the Audience’s Imagination

Sometimes, what’s left unseen or unresolved is far scarier than what’s explained. Ambiguity can leave your audience thinking—and fearing—long after the film ends.

Example:

  • In The Blair Witch Project, the final scene doesn’t show the monster but leaves viewers with more questions than answers, amplifying the terror.

 

Pro Tip: Don’t be afraid to let your audience fill in the blanks. The unknown can be more haunting than the known.
