THE CAVE 2005 Action Horror Film

In the 13th-century Carpathian Mountains of Romania, an Eastern Orthodox abbey and its inhabitants are destroyed by a landslide. Centuries later a group of Soviet and British plunderers are driving in search for the long-lost abbey/church during the Cold War era. They discover the abbey/church is built above a vast cave system, but it is completely blocked off by an intricate floor mosaic. One of the men tries to get the leader of the group to read the designs and images on the mosaic floor. However, the leader brushes him off. The leader looks ahead and sees a spot he thinks they can get through. Wanting to get through to the tunnel, they set up some dynamite. They are successful but not for long, as The mosaic floor splits beneath them and they all fall through to the bottom of a vast cave. The group of men then hear rocks falling and, as they look up, a massive rockslide covers the church and the opening above them. They are now trapped and realize the only way out is to move forward. They descend further into the cave in hopes of finding a way out. They hear strange rattle/clicking sounds in the darkness. This is just the beginning of the movie to set the story.

First thing that came to mind when I heard it was the Carpathian Mountains it had to be vampires. Then I remembered another movie The Descent also 2005 similar in their subject matter that being cave exploration and underground creatures. I also have an idea in my head about what the creature looks like to me but I can't spoil the film.
