Research: Psycho shower analysis

This is to show us how to film a scene with multiple angles, and also use props cleverly, as in this scene, they used chocolate sauce in place of blood, and the stabbing sound effects were made by stabbing a melon.
Psycho is widely considered a classic, and while I doubt our movie will be considered a classic, we hope to do well nonetheless.
