John Cusack, Ray Liotta and Amanda Peet stared in the movie Identity which was given two thumbs up by Ebert and Roeper. The movie is very capturing; it keeps you on the edge of your seat through the whole movie. It is definitely a thriller, but unlike most scary movies it actually makes you think about what's going to happen. It has an attention-grabbing plot with a lot of unpredicted twists. I personal would give this movie two thumbs up.
Ten different strangers are all brought together at an isolated motel due to a viscous rainstorm they had to get out of. These ten characters included: a limo driver, a stuck-up 80's TV star, a cop who is transporting a killer, a call girl, a pair of newlyweds, and a family in crisis. Their relief in finding cover is soon gone and fear takes its place. One by one the ten characters begin to be murdered. Knowing they have to work together to survive, they find out they all have the same birthday. .
At each of the murder scenes they find a room key somewhere on the victim. The murders are taking in ascending order one to ten. As soon as they start to suspect one person or another they too get killed. Soon everyone is suspecting everyone and can only trust him or herself. All of them try to escape from the hotel, but only one gets away alive, the call girl (at least you think). When the girl gets home she is only to realize she still isn't out of harm's way. The least suspected person, the little boy, shows up to kill her.
Twenty or so years later the boy is convicted of six murders. He is also diagnosed as schizophrenic. He was said to have made all of the people at the hotel up in his mind (hint: because they all have the same birthdays). But in actual life he was killing people. They send him to a psychiatric hospital only to escape by killing his own psychiatrist. .
The end determines how you personally interpret it. They don't come out and say who he is actually convicted of killing and where or how it happened.
