Pitch for film

2. Our first idea is that you never really get to know the characters
and you watch them from afar the whole time. You would watch
as this character goes through a mundane life-style but they
notice the same one thing every day –only they can see it. The
sightings of the thing become more frequent until eventually we
see no more of the character (who the audience assumes has
gone missing /been abducted /killed). The film then starts again
but with a new character and then finishes before they also
disappear.
