After completing the storyboards your next tasks are to gather resources and build up a plan of just how to realise your ideas. There are several aspects of your production that need to thought about - these are bullet points below.
Remember, the work your are doing is for Unit 2 which is ALL about preparation and planning for a shoot SO EVERY ASPECT SHOULD BE FOCUSED UPON AND PRESENTED IN THE MOST THOROUGH AND INTERESTING WAY YOU CAN.
First thing you should do is have a Production meeting - take minutes of the meeting, write them up and put them in your folder. The agenda should include:
Evaluation of the storyboards - which storyboard is the stronger, how can you combine your ideas.
Delegation of the roles - who will be incharge of which part of the planning.
What you hope to achieve and by when - set deadlines and work towards them.
Character Profiles: For each character in the title sequence an illustrated A4 sheet giving a brief bio & outline of their role.
Write up their back story, refer to existing characters for similarity of roles, characteristics and traits.
Location Recces: Photos of any places on site they want to use to film, notes on what permissions they'll need and when the location can be accessed. Take pictures yourself - look at Google Earth/Streetview.
Production Design: Photos, drawings of costume ideas, examples of the kinds of props they will want to use, etc. - find pictures, research how you can attain these items.
Casting: List potential actors, find and print out permission letters online, etc - who would be suitable for the roles (they don't have to be you - ask other people in the class or in/out of college)
Typography: Examples of different fonts to use for titles. An A4 sheet with the title of the TV Drama in different variations of fonts, colours, effects, etc. (dafont.com is a good resources - could you make your own font?)
REMEMBER: MAKE THE PLANNING AS THOROUGH AND AS INTERESTING AS POSSIBLE. THIS PART OF THE PROJECT IS JUST AS IMPORTANT AS THE FINAL PRODUCT.
