Centipede! (2004)
Plot: David Stone is a young man about to settle down and marry a wealthy socialite. Before the wedding, he joins his thrill-seeking friends for one last adventure: exploring the unmapped and treacherous Shankali Caverns in India. Accompanied by their guide, Kafi, the group descends deep into the earth, but a powerful earthquake causes a cave-in that traps them miles below the surface. As they search for a way out, they realize they have stumbled into the breeding ground of prehistoric, giant black centipedes. The survivors must navigate the pitch-black tunnels and their own internal conflicts to escape the venomous predators before they are picked off one by one.
