Lily's character shows how the life of a young girl gets turned upside down by war.
It was filmed for the charity Save the Children as part of their Save Syria's Children appeal.
Lily has just finished filming the Hollywood film, 'A Monster Calls', that's set to be released next October.
Lily wants to become an actress when she leaves school but says, for now, she wants to focus on going into Year 8 and looking ahead to her GCSEs.
