Jim Carrey reteams with his Batman Forever director, Joel Schumacher, for this dark psychological thriller, which revolves around a man who becomes haunted by the fact that he's reading a book about his own life . . . and that the book ends in his murder. The Number 23 is both the title of the film and the book within the film, and the number 23 is intertwined in the plot of the novel and, therefore, the man's real life.
