He was inspired by a trip he took on an Easter weekend to an isolated beach in New South Wales: I started LW as a way to avoid the TV-cop-show doldrums while still convincing myself I was "working".

LW was a unique project because I began with no outline, no notes or research, very little idea as to where the story was going, and absolutely zero knowledge of screenplays.
