It could imply that there is a real - life situation where extreme anger or vengeance is involved. Maybe it's about a story where someone was wronged in a very bad way and their retaliation was fierce, just like the saying 'hell hath no fury like a woman scorned', but in this case, it's based on a true event.
There was a case where a woman discovered her husband had been having an affair for years. She was so enraged that she exposed his infidelity to his entire family, his workplace, and all their friends. She also took him to court for alimony and a large share of their assets. Her anger was like a storm, and it was all based on the real pain and betrayal she had experienced. In this case, it was truly 'hell hath no fury based on a true story'.
I'm not sure specifically as I haven't read it. But generally, it might be about revenge since 'hell hath no fury' often implies extreme anger and vengeance in literature.
Well, it might be special because it could explore the darker sides of the Potter universe in unique ways. Fanfics often take the existing world and add their own twists, and this one might be delving deep into the emotions like fury, perhaps showing how characters react to extreme situations in ways not fully explored in the original books.
One possible theme could be revenge. Given the 'fury' in the title, characters might be seeking revenge for past wrongs, like a character who was bullied at Hogwarts getting back at their tormentors later in life.
Indeed, 'Fury' is based on a true story. The film is set against the backdrop of World War II, and it incorporates many aspects of what actually happened during that time. It gives us a glimpse into the lives of soldiers, their training, their relationships, and their fight on the battlefield. By basing the story on real events, it allows us to empathize more with the characters and the situations they were in, and also provides a historical perspective on the war.
Fury is purely fictional. It doesn't draw from any real-life incidents or people. The story was developed to captivate audiences with its action and drama.
