10 Horror Movies That Deserve A Sequel (But Will Never Get One)

10. The Belko Experiment

Written by James Gunn, The Belko Experiment takes place in a high-rise office, where employees are ordered to kill their co-workers until only one remains. Almost immediately, long-time colleagues, friends, and lovers turn on each other, desperate to save their own skin.

In the end, resourceful worker Mike is the victor and seemingly puts an end to the grisly contest after slaughtering the orchestrator, but in the final moments, it's revealed that similar experiments are being conducted across the world, and this organisation is prepping for "Stage 2".

Even without the sequel bait, it was obvious The Belko Experiment had plenty of opportunity to grow, especially if the same scenario took place in a different environment. Imagine if the competition occurred at a sporting event, a prison, or a wedding? A follow-up could look at multiple scenarios simultaneously, each with different stipulations.

Rather than repeating recycling ideas, the next instalment could centre around an investigator or a former survivor uncovering Belko's origins or their intentions for the future.

Even though the sky's the limit, The Belko Experiment remains a standalone story.
