Possible Shot Idea

This effect is a chest cam which is used in some films to show the characters facial expression whilst they are walking. A notorious use of it is in trainspotting to show Ewan McGregor's facial expression whilst he is suffering the affects of drug use. We can use this effect in our trailer to show a characters expression, we would probably use it to show the husbands expression once he finds the ransom note on his desk and show his breakdown of anger and fear.
