Well, what a difference a day makes!
After a discussion about Who Killed Randall with the writer/ director, Benedict Sampays, it has now evolved.
While driving back from London, a discussion about where the storyline could be tightened or tweaked started, which ended 2 hours later with a new twist, new character profiles, new ending...in fact, all that remains is the main spine of the story. Around this spine, there are now numerous sub-plots, that twist and turn around each other. The synopsis now reminds me of early Guy Ritchie plots, with all characters interacting and eventually meeting at key points.
Benedict is now turning this new synopsis into a first draft of the script with a deadline of the 1st March.
