How's this idea for a faux documentary thriller.
By that a movie like Paranormal Activity or The Blair Witch Project. Like those thrillers a camera will be used in the sense that it is found footage or of that concept.
An undercover cop wears a micro camera in his jacket that sees everything he is facing, and the whole movie is surveillance footage from that camera. However the question is, will the audience find it hard to watch, if you have seen what those cameras look like, plus they are always pointed at other people's chests, so the audience will have to look more up in the point of view. Good idea for a crime thriller? Not sure if I would write it or do it, just contemplating it right now.
