Really long time ago I saw a movie, but I can`t remember the name.

The things I remember was that a man and a woman went to look for a special butterfly (adventure film). They discovered this land or city of women. There were no men, so the man was captured. They made the women fight which one gets the man. And in the city there were crystals. That is all I can remember.

Thanks for everybody who helps.

Was it one of those "late night" movies with Julie Strain?

No, it wasn`t an adult film. I think the girl was blonde.

I might be way off here, but it sounds like Gwendoline (1984) (http://www.imdb.com/title/tt0087903/)

Jep that is the one, thanks.

You're welcome.
