…investegating about the movie in theaters and find a strange picture hidding in the movie film. It isnt visible on screen only when you look at the film itself.

As the title says its a movie about people starting to randomly die. A couple of unpopular kids fro, a high school where some deaths have occured start investigating and find a face of figure on the movie film(negative) that doesnt actually appear on screen  since thers only one or two frames of it. Only people who have been to the theater to see the film die.

I saw this movie between 2003 -2008 probably.

The highschool had an indoor pool, i think a murder happened there, possibly in the changing room shower i think it was the girls shower. She thought her boyfriend was coming to meet her or maybe he did and they had sex then she or both of them died.
