Film Title

We have almost finished our clip now, the only thing left to do it to think of a title for our film and add it in to the credits. We decided it should contain the word "letter" as our film focused on the letter quite a lot. I think it should be quite a simple title. Some suggestions i was thinking of were "Letter Man" or " Dead Letter". I prefer the second one out of these two titles as i think it sounds more myterious and more like a thriller than the first.
