Protagonist! 

Design: A.K facial expressions concept art

I would need an actor whose voice can appear younger, it might have to be a girl pretending to be a boy. While I am unsure of what accent A.K would have, his voice would be anxious and almost angry; he is trapped in a horrible situation despite his young age, and is forced to understand the world from this perspective.

A.K is a 10 year old boy living in a world where climate change has doomed Earth. As the richest members of society leave on space ships, his father joins the military to ensure them a place on the escape ships despite their poverty. However, due to his low rank he is not allowed to take his family. The film follows A.K's struggle as his father is unable to get him tickets onto a spaceship and he is ultimately left behind with his mother, forced to survive on a ruined Earth. A.K's character represents the endangerment of future generations due to the lack of protection of Earth's climate; he is a tragic character and should be voice acted with this in mine.
