Hello
I saw this film few years ago but can’t find name.
Woman look for lost prince, she finds him and protects him from enemies. She wants to help him to be king. But firstly he doesn’t want to be king, but woman effects him to believe.
At the end woman died while protecting him. She was brought up for this mission.
Then man made his army and getting ready to be king.
How about “The Eagle” (2011) by Kevin Macdonald?
