Been trying to track down movies that I saw as a kid using little more than keywords. I've found most of them but there is one that I can't seem to figure out at all, so I'm asking all you Moviephiles out there. All I remember is a single scene at the end of the film:
A man is unlocking three boxes or treasure chests, in which are powerful artifacts (possibly crowns). When he opens one of the boxes his head spins around similar to Regan from Exorcist. I think each box does something to a similar effect. Meanwhile, the villain's face begins to spray blood, he's screaming as this is happening and I think there are designs being cut into his face from this blood.
That is really all I have to go by. The movie is possibly a Martial Arts movie and is likely to be from the 70-80s era; my guess is some point around Exorcist and Raiders of the lost arc.
So, any suggestions would be helpful. Thanks in advance.
