The word 'mnemophrenia' was coined especially for the film. It's a portmanteau of the words 'mneme' and 'schizophrenia'.
In the film 'Mnemophrenia' the word is defined as: 'A condition or a state characterized by the coexistence of real and artificial memories, which affects the subject's sense of identity.'
The director, Eirini Konstantinidou, used improvisation in order to build the characters and the shooting script for the whole film. She believes that the realistic dialogue and performances that are achieved through improvisation contribute to the intended blurring of the distinction between reality and fiction.
Part 1 needed to be made first and edited in order for the actors of the following period (part 2) to watch it and build their characters' experiences from what they have watched; according to the premise of the film these video recordings become part of their memories and identity. That is the process that the actors of part 3 had to go through as well. This technique allows for an organic development of the characters and dialogue, which is a result of the creative collaboration between the actors and herself.
