That actually reminds me, I had an idea for a horror film when I woke up this morning.
A demon that knocks 3 times, like someone is at your door. And characters keep going to see who is there, but nobody ever is. But then it starts knocking inside the house. Driving people crazy and making them agoraphobic shut ins. And eventually, the demon is actually behind a door when they open it (cue jumpscare).
I call it Three Knocks. Underlying themes about fear of neighbours and police etc. No stealing Hollywood lurkers.
