In the past i have watched the film 'The Panic Room', recently i came across it again and i have to say its one of my best thrillers.
Its a Phsycological thriller. Jodie foster plays a woman who is newly seperated from her husband and is living with her daughter. they buy a huge house that happens to have a speciall room called a panic room. This thick steel lined room is intended to block out intruders. They spend most of their time in the panic room trying to survive.
