Director- Alfonso Cuaron I picked him because of his famously long panoramic action sequences. Known for Gravity and Children of men.
Joel- Russel Crow...... Watch NOAH
Ellie- This is a hard one for me. I don't know any young actress'. But just because of the resemblance I want to pick Ellen Page.
II haven't thought to much int o the actors but that director is perfect. I seriously doubt he would get on board though. Anyway, Let's hear more suggestions.
