Why did they make a movie of bloody marry?

There is no widely recognized movie about Bloody Mary, the legendary spirit. There are many movies that feature characters named Mary, but none directly based on the Bloody Mary legend.

It's possible you might be thinking of:

* "The Conjuring" (2013) and "The Conjuring 2" (2016): These horror films feature a scene with a young girl playing the Bloody Mary game, but this is a minor part of the larger storyline.

* "Urban Legend" (1998): This horror movie features a scene inspired by the Bloody Mary legend, but it's not the central focus.

* "Mirror, Mirror" (2012): This dark fantasy film features a villainous queen named Queen Clementia, who could be seen as a modern interpretation of a Bloody Mary-like figure.

While there are no movies directly centered around the Bloody Mary legend, the legend has influenced many horror movies and continues to inspire filmmakers.
