The secret of Secret Window becomes obvious fairly early, so thankfully there’s one thing more crucial to the movie: Johnny Depp. Depp has become more squirrelly as he’s aged, and as a mystery writer tormented by a mysterious stranger (John Turturro), he
brings unpredictability to the screen without ever stepping outside of the story. The plot itself comes from a Stephen King novella, adapted by writer-director David Koepp (Stir of Echoes).
