Dagger Scene

If I were a director and had to film the dagger scene, I would not have an actual dagger in the scene to prove that Macbeth is going insane. I would not have a dagger in the scene because without the dagger in the scene it would make Macbeth seem like he is going mad. Macbeth says "Is this a dagger which I see before me/ The handle toward my hand?" (2.1.33-34), when he says these lines without a dagger in front of him, it makes him seem "crazy" and that he's imaging things. Without a dagger, it would prove the fact that Macbeth. In my opinion, if there was a dagger in the scene, I don't think everyone who is watching will be able to understand that he is only imagining the dagger. Without a dagger in the scene it helps the audience understand that Macbeth is really only imagining the dagger.
