I saw it in 2012 or 11, might have released then or before. I don’t remember the actors. English hollywood film, colour definitely. So what I remember is there was a loving couple and then there was this doppelganger of the husband who manages to sneak in. The wife somehow finds this, may be it was his ways or he himself who disclosed it. Then she was raped. I couldn’t see the conclusion of the film and that is exactly why I am looking for it’s name.
