Casting

Brief-
Male aged over 40.
Teenager female aged ~17

Who?
Mike Timson- We would use him because of his features, and willingness to act.
Backup?
Mike Niland- He would be able to act as a backup, because he is set aside time to help us anyway.

Person In the Industry?
Stellan Skarsgard- He has extraordinary acting skills, and has mature/aged looking hands.


Who?
Mia McCallum- Has acting experience, has smooth skin, so the macro, closeups would not show so many imperfections.  


Backup?
Edwarda Martinas- She has young looking skin, and is talented in acting. She is studying GCSE, so she will be able to take time from lessons to act.

Person In the Industry?
Masie Williams- She would be perfect because she has very perfect skin, and her skin color is pale, meaning it would be easier to pull off that she was dead. She also has young looking skin, making the character look more vulnerable. 

I find the contrast between a man and the younger girl creates a effective cruxterposition.
