Development of Story line

Me and my group discussed our ideas of having an unrequited love theme but we thought it would be too cliche and un-original. As we are doing a psychological thriller we decided to keep the same obsessive theme in the story but change the way we showed it. Firstly, we are using one proganist and one (maybe two) antagonist. The relationship between the characters will come across very misleading as they are brother and sister but because of there past and what has happened the stereotypical relationship of a brother and sister is ruined. 

A summary of the story line  The brother went missing a long time ago and the sister who was slightly younger was so upset and depressed that her brother has gone missing that she has become mentally ill over the fact he has gone. However, he then comes back but, because she is mentally ill she doesn't understand the fact he has returned and been found so she ignores his return by ripping up news paper articles of "boy ages ** found!" - We are then going to show the brother, looking very casual and smart (looking rather normal) to convey the juxtaposition between both their lives. It also highlights her obsessivness over him and how she couldn't deal with the matter. 

Order of clips shown:
Even though we haven't talked about a shot list, and what kind of shots we want to appear/when etc. We have decided the order of how the opening sequence will go.

• First shot will be introducing the title of the film company
• Will then go onto a shots of the protagonist, looking stressed and mentally unstable
• Title will appear very fast and bluntly
• The antagonist will then be shot, looking smart and doing day to day things so the two shots are contrasting a lot but the title of the movie will split them up

Me and my group still have a lot of things to think about such as the:

• Costume?
• Lighting?
• Camera shots
• Editing
• Title colors
• Title of film
• ETC
