When I was a kid I watched this animated movie about a girl who is saved by a soldier in a war... he gives her something and she falls in love with him. The girl lives a impossibly long time trying to find him again. She goes from a ancient japanese war to traveling somewhere in a space ship at the end of the movie.I think that it was an anime movie, though I couldn't tell the difference when I was young. I have absolutely no idea what the name is and its killing me. Help!!

Sounds like,.

Millennium Actress

But she didn't actually live in feudal Japan, or live to see the distant future. Those were movie roles that seemed to overlap reality in her mind.
Each role she took seemed to repeat the theme of a heroine's search for an elusive lost lover.
The young woman was always an obedient child to her overbearing mother, but a chance encounter with a young man on the run from a group of government agent motivated her to commit her first act of defiance by helping the injured man. She hid him and nursed him back to health. He couldn't stay and was soon on the run again. She took her first movie role against the advice of her mother because the movie would be shot in the city that the young man had been trying to travel to.She hoped they'd meet there
She continued her search for the young rebel she'd fallen in love with through her entire life, both on and off screen.
