Alterations to Proposal

The things that i could improve on were my marketing, as i had not really thought about it. Also, i could improve on the choice of actors and actresses, and possibly change who would play Sarah Brown. I would probably choose someone younger in order to widen my target audience out more. Any alterations i have made are in RED.
I was also thinking of changing my film title to something more dramatic, as the plot is fairly dark and emotional, and "uninvited guests" doesnt really suggest that (in my point of view).
