Sadly, I don't have the exact details of the true story behind 'The Stranger' film. But it could potentially be related to a real - life situation where the appearance of a stranger disrupted the normalcy of someone's life. It could involve themes like trust, fear, or the unknown, which are common when dealing with strangers in real - life situations. The filmmakers might have taken this kernel of a true story and built on it, adding their own creative twists and turns to make it into an engaging film.
I'm not entirely sure about the specific true story that inspired 'The Stranger' film. It could be about a real - life encounter with a mysterious stranger, perhaps something that happened to the writer or director.
Well, without in - depth research, it's hard to say precisely. However, it might be based on a true - life incident where a stranger entered someone's life and changed it in unexpected ways. Maybe it was a story of an encounter that had elements of mystery, danger, or a profound impact on the people involved, which the filmmakers then adapted and fictionalized for the screen.
