If you have a film that takes place in a prestigious university and that involves the use of mathematical symbols in order to solve murders, I think you can do a lot worse than using the imagery of a blackboard filled with mathematical mumbo jumbo and splattered with blood. The blood splatter in this poster looks particularly fake, but besides that I think it’s a decent execution of the concept.
This is not a terribly memorable poster, and it’s no likely to win any awards. But it does get the point across.
Looks like “Sweeny Todd” meets “The Number 23”
