Haven't watched it. But it does look interesting from the trailer.
It's about a writer whose story happened in his real life, too. And he felt someone (or rather: some "unexplainable super force") tried to kill him?
Is the description close enough, loveflower?
Let me recommend another movie: Music and Lyrics. Also about people who write, but this time of course it's writing lyrics instead of novels.
It's about a 80s star (Hugh Grant) who tried to become famous again (it was almost his last chance) by writing a song for a super-famous young singer. He wrote it with the help of a talented yet with low self-esteem girl (Drew Barrymore).
