All I really remember is there were hooks on the ceiling and they had gravity boots and they were fighting upside down. I want to say the movie had vampires or elves?
It was a newer (last 10-15 years) movie, english mainstream type of thing. I don't remember the genre, but it has its action moments and its smart a$$ one liners. I think the protagonist was a somewhat unlikely hero, and I think maybe they infiltrate this cave of bad guys, but they're ill prepared, as they don't have the fancy boots with hooks on them. I think the guys defending their lair have curved blades, and at one point someone is hanging precariously from the rings on the ceilings that serve as foot holds. I'm pretty sure they end up getting captured.
I'm not certain, but I think they infiltrate the cave by stealing/stowing away/riding a ship/animal that the "bad guys" use as transportation. That's why they were unprepared for the lack of floors when they get there.
