Research and Planning: Test Shots for magazine

Here is a male model who would be well suited to the role of the tall male lead, who is focused on his task of discovering what's happening. He would be able to tower over the female lead and looking physically more powerful than her.

 Becky may be suitable for the female lead because she is so tiny and innocent seeming, however it would be very difficult to make her look as though she were dead, as her hair and expression appear to be very full of life. 

Sam is not really suitable to play the part of the male within the trailer as he is quite thin and not very powerful looking. He is also not very tall, so his height in relation to the actress used may then have become an issue.
