Title

A key part of creating a film is coming up with a good title. Therefore we wrote the plot first and then came up with titles that alluded to events and concepts from within the film. For example:

As Yet Unknown was the first suggestion, referencing the fact that Holly didn't know what was going on and who, if anyone, was hurting her friends.
The Unknown was clearly a very similar suggestion to the previous one, once again referring to the fact that Holly didn't know what was happening. It also simply refers to one of the biggest fears of many people.
Isolation was suggested because throughout the film, Holly pushes everyone close to her away until she has no one - she isolates herself.
All Eyes On You clearly connotes the idea of being watched, and although I believe it is an effective title, we found that as we developed our plot and ideas, it didn't quite fit with the storyline.
Secrets, as a title, would allude to the fact that Michael was responsible for Holly's misfortune, however this wasn't something we wanted to make clear until the end. In addition, there is a film from 1992 called Secrets and a film from 2007 called The Shadows.
In The Shadows was the title we chose to use. It was more obscure than The Unknown but still suggested the concept of unknown and unfamiliarity. It connotes that the supernatural may be involved but still fits, perhaps even better, when the audience discover that Michael is the problem.

We were worried that there would already be a film called In The Shadows but after investigation we could on find the 2014 film What We Do In The Shadows. Although it was released recently, we hope that there will be enough significant differentiation between the two films for them to be easily distinguishable, especially as they have different genres with our film being a horror/thriller and What We Do In The Shadows is described as a "mockumentary horror comedy".
