A few years ago I watched a movie that opens with a somewhat arrogant editor/publisher type guy who keeps promising to get around to reading his assistant/secretary's manuscript, but never does.
Some weird stuff starts to happen and he finds out that someone is watching him and he gets pretty paranoid. At one point he sees someone in a nearby apartment watching him with a telescope, and he breaks in to find that it's the aforementioned assistant. She claims to be stalking him out of romantic interest, so he continues thinking someone else is after him and ends up killing a security guard in his paranoia.
Eventually we learn that the security guard and some other people were aspiring actors hired by the assistant. The man reads her manuscript and realizes that it's the story of what just happened to him — she orchestrated everything in order to blackmail him into publishing her books.
Can anyone identify this movie? This question reminded me of it, but neither answer is what I'm thinking of.
