The story about a nurse named Cora that Josef tells to Hanna is a short-story named "La señorita Cora" by argentinean writer Julio Cortázar from his book "Todos los fuegos el fuego".
The contact lenses damaged Tim Robbins' eyes. An ophthalmologist has required on set for a few days to supervise because Robbins refused to take them off.
In order to fly out to the rig, Hanna would have had to do a three-day off-shore survival course. There seems to be no indication that she does this in the film.
When she arrives at the oil rig by helicopter, Hanna is not wearing a transit or immersion suit. Wearing this is obligatory when travelling to off-shore installations in the North Sea.
Inge: Before the holocaust, Adolf Hitler called all of his collaborators together and in order to convince them that he could get away with his plan he asked them who remembers the extermination of the Armenians? That's what he said. Thirty years later nobody remembered the million Armenians exterminated in the cruelest possible way.
Hanna and Josef have two kids together. During the war in Yugoslavia
she was held captive in a hotel, tortured and raped. There is some debate as to whether the voiceover narration is in the voice of an unborn daughter of Hanna's (possibly aborted), the personification of her survivor's shame, or if she was the mother who was forced to kill her daughter in the story she shares with Josef.
