The others, Alejandro Amenábar

I like this film because you don't know whats happening at all until the last moment. And you don't expect the film to end like that. It is very original and I had never seen anything like that.

A mother and her two sons live in a mansion in Jersey just after the World War II finished. The children Anne and Nicholas have an uncommon disease. The sunlight cannot touch their skin because otherwise they will burn. One day, Anne draws a four member family: a man, a woman, a child named Victor and a old woman. She says she has seen them a lot of times. The mother, Grace, doesn't believe Anne until she sees the ghosts for herself. Charles, the father of the children and Grace's husband returns home one day. Everyone thought that he died in the war but aparently he didn't. The next day Charles says he must leave to the front and disappears again. Nicholas and Anne sneak outside the window to find their father and instead, they find in the garden the graves of the servants. At the same time, the mother discovers that the cleaning lady, the cooker and the gardener all three died for tuberculosis more than 50 years ago.
The mother hides the children but the strage old woman find them while she is acting as a medium with Victor parents. And the truth comes to light: Grace, Nicholas and Anne are the actual ghosts. Many years ago the mother killed the two children in a fit of phycosis and then she shoot herself. Victor's family, scared to death leave the house and the property is put up for sale again.
