Title (no longer) Pending....

One component that horror/ thriller movies have is that ominous title. Usually its not too long and it serves as intrigue and mystery. For example, the movie Split has a one-word title and the movie technically is relevant to the title. However, the word "split" is ominous and does not give too much of the plot away. Short titles such as Saw, Psycho, and Scream all have ominous, and effective ways of striking intrigue in the viewer before they even press play.
The exceptions to this rule include The Silence of the Lambs, A Nightmare on Elm Street, and The Texas Chainsaw Massacre. However, these titles still have a very ominous tone, and therefore are very effective. They also make use of usually frightening words such as "silence", "nightmare", and "Texas" "Massacre".
For our movie title, Ricardo and I decided to stray from the usual one or two sentence titles. Ricardo was heavily inspired by a poem written by Stéphane Mallarmé. This specific excerpt was where he drew the inspiration.

So we introduce to you our film...

When We Keep Silent

We believed this title was effective because although it was long, it still kept the ominous tone as other long titles did, and we even kept the frightening word "silent". It also was not too long, and overall became kind of catchy after a while. 

The poem touches on how it is hard to understand ourselves and the world around us. This ties in to Trevor's story perfectly because it is hard for him to understand his feelings, and it is hard for his victims to understand his unusual behavior.

Furthermore, this title, I believe, is a great fit.
