This is a bit of a long shot since I don't remember anything from this live-action movie or TV series episode except for this one (hopefully memorable) scene. It's actually possible I didn't watch the whole thing, just this scene. I watched this as a kid on TV, late '80s to mid '90s. Probably in German, but since I don't remember any actual dialogue at all, it's also possible I watched this while on vacation, in France or Spain.
- In the scene, there was a round table or wide pedestal with a hole in the middle. Swords were lying on the table, arranged in a star pattern, with their tips pointing toward the hole, pommels outward.
- People were standing around the table, chanting something. It's possible these summoners were all female. I think it was some interior location, but not sure.
- As the chanting grew more and more frantic, a greenish apparition started forming above the hole, becoming slowly more opaque. I think the apparition resembled a knight in armor, but I might misremember that.
- The summoning was interrupted by one or more people arriving at the scene. One of them drew a sword or a saber, whereupon the apparition vanished with an inhuman wail.
- Finally, the swords on the table were cast into the hole.
Does anyone recognize this?
Update: Qev's answer suggests the movie Red Sonja, but this is not what I watched. I remember:
- darker lighting than in Red Sonja,
- more rhythmic chanting, getting almost frenzied towards the end, with the summoning almost complete (whereas in Red Sonja, the ritual is interrupted pretty early on in its progress),
- the swords were lying on the table (possibly in sword-shaped indentations, though I'm not sure), not being held,
- the table/pedestal didn't split, there was a static hole in the middle, too small to throw a person in, but large enough for swords,
- a green spirit with a humanoid form, not a talisman. The spirit didn't disappear soundlessly like the guy in Red Sonja, but vanished (evaporated?) with a wail when threatened with a sword/saber.
- the swords being cast into the hole simultaneously (whereas in Red Sonja, the priestesses are cast into the hole one after another).
Nevertheless, the setup as such in Red Sonja is so eerily similar to what I remember that I'm now wondering whether I'm conflating multiple things in my memory, or (hopefully) someone took a page out of Red Sonja's screenplay for their own production.
