Secret Window (2004)
Given the title and the thriller-like quality of Secret Window, you might think it's a remake of Alfred Hitchcock's paranoid classic, Rear Window. And again, this doesn't veer completely into the horror genre. It's actually based on a Stephen King novella called Secret Window, Secret Garden. Starring Johnny Depp and Maria Bello, it follows a writer who is accused of plagiarism by a dangerous stalker.
