Provides Examples Of:
- Color Wash: The scenes outside blow out the color, giving an orange wash.
- Cruel Twist Ending / Gratuitous Rape / No Ending: One of the most egregious and notorious cases in recent memory. At the end of the film, the caveman (Petr) brutally kills one of the remaining survivors and rapes the other, and the film just ends right there.
- Epileptic Flashing Lights: Basically the only source of light are the characters' flashlights. And they flicker to the point of inducing seizures.
- Follow the Leader: It was filmed as WIthIN, but released on video as The Cavern to cash-in on The Descent and The Cave.
- I Ate WHAT?: The two Final Girls eat some meat... and find out it's man one. Puking ensues.
- Stranger Behind the Mask: In the final moments it's revealed the monster was a caveman whose origins are shown at roughly the same time.
- Too Dumb to Live: All of the protagonists, since they have insufficient equipment.
