Here's all I can remember about the movie.

It was an animated movie in the vien of Flight of Dragons/Last Unicorn, only a little darker feel.
I watched it some time in the early 80's.
There was a guy and a girl as the main charchters.
The guys name was Serious
The girl had a cool accent.
There was a scene where they were in some flower puff/fluff stuff, floating through the air.
I remember the girl calling the guys name out as they got separated.
I think there was something about the boy loving the birl but them not being allowed to be togther because she was a princes or something. Im not sure about this since it has been so long but its all I have to go on.

Any suggestions?
Thanks, Morgan

It was called The Sea Prince and the Fire Child.

Oh my... thank you that was it. I have thought about this movie for so long and had no idea about how to find it. Thank you so much. Morianna

Sadly its very hard to find. I don't even think a DVD is available. I checked Amazon.com and only found a VHS copy. Good luck.
