PLEASE HELP! The movie was about a girl whom I believe was transported from the future. She had long black hair, and I remember she had a type of tiara that looked like white plastic with a large stone in the middle. The only other thing I remember is that she put her clothes in the microwave, because in the future that was how laundry was done. Like I said, I think it might have been on the disney channel, I believe it was made for TV.

This question has cropped up several times now and to date I have been stymied in finding the answer. Until I figured out a way to research this on another site and rip off someone else's answer. It is not exactly a movie you are thinking of, per se, which is why all of my previous searches have failed miserably. It's an Australian miniseries called The Girl from Tomorrow, which aired in 1991. Parts of it were then edited into a movie in 1992, and a follow-up mini came along in 1993. Hoody hoo! I am the champion! Kneel before Zod!

Its called "the girl from tomorrow" I thought it was a movie too but its actually a TV show lol I guess I was real young and thought it was a movie or maybe it was just a marathon when I seen it lol

I know what your talking about the tiara was called a transdusor... can remember the name though
