Oh they probably saw it as a good fit for this movie. After all, you would see some "indiana jones-ish" story parts. Hitting and braking stones with head, hand, kick and probably other anatomical parts too 🙂. Shouting at the stones and make them brake (ok this part isn't in the movie, but still, it was funny to mention it, some crazy stuff after all hehe). Oh and one part of the movie when people start to jump 10-20 meters. I mean WTF? Probably the movie "Hulk" has got his ideas about jumping from this movie 😄
Watch, then post your comments...ROFL!
