My idea for a thriller film...

My idea for a thriller film is that a mental patient escapes from an institute and runs riot around the city, he kills anyone that he comes into contact with, we can take some shots like the one that you see to the left of someone sitting in the bathtub with blood dripping down the walls, or dripping down the side of the bathtub. we can buy some fake blood from the shops and use it to add a horror vibe to our film.

We can also have a shot with the psycho sharpening his knives in the kitchen, or wiping the blood of his face, I also think it might be a good idea for the psycho to lick the blood of the knife to make it more realistic.
