I remember this movie coming on numerous times on HBO and Cinemax when I was a kid and I watched it every chance I could. I know now that it was a cheesy movie and if I watched it again it would probably be not as good as I remembered, but I did like it when I was a kid. Sure most 3-d movies do the hokey sticking stuff in your face routine, and this movie is no different, but I still enjoyed it. Even though during one scene of the movie you can see the string on the "flying" key. The parts I enjoyed most are the first and last parts of the movie. The lead guy in the first part has to get through various traps to retrieve this key thing. I always love boobey traps. The middle just consists of him recruiting people to help retrieve the two crowns. Then it is like a spy movie as they break into some cults palace that has numerous traps. And yes there were only three crowns, one only had paper, the other two had gems, the forth one supposedly was broken by someone who tried to open it without the key. I don't think this was in the original foriegn version. I think it was mentioned only because Treasure of the Three Crowns just doesn't have the same type of ring to it. In the end many of the characters die, and perhaps they get the stones or not...I would say but I don't want to spoil the really dumb ending.
