Robert De Niro is such a random actor. This Movie kept me wondering, then the surprise. . But it was a tiny bit strange to see Dakota playing a role of "disturbed" kid.
The House was so cute they lived in.
After the police discover her car crashed near David's house, David asks Emily what happened. Emily claims Charlie had caused her death and then tells David where her body is. A terrified David discovers Elizabeth's body in a bathtub full of blood. David asks Emily where Charlie is, and Emily tells him that Charlie "just left the house". David, armed with a knife, goes outside, where he meets his concerned neighbor that has become friends with Emily. The neighbor claims he heard noises and saw David walk out of the woods with a shovel moments before. David assumes that his neighbor is Charlie and begins to act aggressive. Thinking that David has killed his own daughter and buried her in the woods, the neighbor asks to see Emily, but David refuses and cuts the neighbor with his knife. The neighbor then calls the police. As he is in his house a door opens. David thinking it was their neighbor he goes armed and ready. Nobody is there just boxes and his psychologist equipment. After this, David discovers that he has split personality. David realizes that Charlie is not imaginary at all, but that in fact, he is Charlie.
