My dad want's to see a movie, but he can't remember it's name.
About it: Dad and boy went to an expedition, but there was air crash. Survive only boy in this crash. Boy was saved by king, and king rise him as his son. King also had a son, he was evil and want throne. But king gave throne to his adopted boy. When boy grow up, he went to his country (dad think it's America), boy's mom recognize him because of his medallion.

So if you know about what movie I'm talking please write its name.

Thank you very much in advance.
