Caved In: Prehistoric Terror (2006)

Caved In: Prehistoric Terror is a "Sci-Fi Original" motion picture, created by the Sci-Fi channel. It follows a party of tourists who become trapped underground by a cave-in, and who are then killed one by one by giant prehistoric rhinoceros beetles.

The movie is infamous for its not-so-subtle "kill lines." These kill lines are lines said by actors right before they are killed, essentially telling the viewer how they will be killed. (e.g. right before getting one's head sliced open, one would say, "Argh, I have a splitting headache!") It is just one of the many Sci-Fi originals that is focused on being trapped in a confined area while being hunted by mutated species.
