The main actress

Chloe and I had the following ideologies of the young female character we wanted to act in the video:

• Innocent looking
• Pretty
• Sweet
• Captivating

Therefore we cast Ellie (my boyfriend's younger sister) who I knew would be confident and happy to act as this young girl. Her long curly hair and big brown eyes add up to her looking both innocent and beautiful. We thought her especially perfect for the introduction, when sat in the middle of the lamps in a dark abandoned room in a white dress - since we knew that she could easily look scarcely beautiful in this situation which was the look we were aiming for.

Also, since one of our ideas behind the video is a violent/difficult father-daughter relationship, since I know Ellie well, I could ensure that she was wholly comfortable with this concept.
Not only this, her dark hair would fit well against white/light day backgrounds and when we wanted to merge her into a dark background in order to represent her as invisible and unnoticed, this would be quite simplistic and easy to do.
