I am a person that grew up in the 80's and I can for some reason not remember for the life of me what the name of a movie that I have been looking for almost 12 years now.

All I can remember is that there is a male and female lead characters and that they are forced from their home for the planet is breaking apart. The planet as it breaks apart around them it seems to look like a tetris game screen coming apart and it all just falls down and away. Some of the people in the movie also seem to freeze in a special way where they seem to look like tetris blocks.

Please help me find out what this movie is I would love to watch it again with my wife and children now that I am a father.

The Langalores maybe?

Sephen King

Sorry but that is not the one maybe this will help the movie was fully animated in color with great detail

Possibly Unico: In the Magic Island.
Unico: Mahô no shima e (1983) (http://www.imdb.com/title/tt0086515/)

We are getting closer I can feel it but the characters where older in the mover and there was no unicorns but that I move was another I was looking for and was going to post about later this week thanks for saving me the trouble but I am glade we are getting closer to the one I am looking for
