Role Of Writers Throughout Production.

Pre-Production

This phase of the project is where all the planning and developing takes place before the camera films. This planning phase sets the overall vision of the project and that can take any amount of time from minuets up to days. Pre production also includes planning out the locations to film and people to cast. At this point story boards will be used a lot and they can help smooth out the process for when its time for editing this is also really help full if there are multiple people working on the project.

Script Editing

Script editing or more commonly known as a script editor is a member of the production team of scripted television programmes, usually dramas and comedies. The script editor has many responsibilities including finding new script writers if needed, series ideas with writers and developing storylines. Also ensuring that scripts are suitable for production. Script editors usually work up through development or come from similarly creative editorial roles in other media such as theatre. This is also a frequent step in the road towards producing. Feedback for the writer will be overseen by the script editor, building up a relationship to help them judge how best to provide notes on the script and which areas to leave alone when they suspect the writer will iron them out independently over a process of drafts.

Director/ Producer involvement

A film producer fills a variety of roles depending upon the type of producer. They plan and coordinate various aspects of film production, such as selecting scripts, coordination writings, directing,  editing and arranging financing. The producer has to find promising material during the discovery stage. A screenwriter is then found if the film is supposed to be based on a original script.

Shooting Script Production

When a screenplay is approved for production, the scenes are assigned numbers which are included in the script alongside the scene headers. These numbers give a convenient way for the different production departments to reference individual scenes.
After a shooting script has been widely circulated, page numbers are locked and any revisions are distributed on revision pages.
If the assistant director believes that there are more changed pages than are worth swapping out, the script coordinator may issue an entirely fresh script in the appropriate revision colour. In some cases before the start of principal photography a entirely new "white draft" will be distributed in lieu of coloured revision pages.

Page Lock Down/Adjustment During Shooting Stage

During this stage there will be no more rewrites or edits, the script will be published and handed to the departments. If in some cases the any scenes do need to be rewritten and changed, locking the pages allows this to be easily tracked, so it keeps the revised and unrevised pages separate which will show the difference between the original script and the changes.
