All of it forced the actors and the audience to eliminate that sense of fantasy in a play. Because the actors were completely surrounded by people and because the people could see everything the actors did and they would address the audience it forced everybody to be included. Some other facts that i found out, when we think of Shakespeare's "to be or not to be" monologue we assume that he didnt address anybody and that it is in all of his head or he is talking to himself. When you are at the Globe theater you realize that he couldn't help but not address the audience when he talks, so in fact he is talking to the audience when he did that speech. Also i learned why certain things are called what they are.
When a person says that they have a roll like ( i have the role of Juliet) its because back in the day they printed their lines on actual roles. And not only did the roles have their lines, but also only had their que lines before their own. So each actor only had their parts and no one elses. So every single play was basically improve because they had about 2 weeks to rehearse and about 2 hours a day to do it. These facts amazed me, perhaps its because i'm a theater minor or maybe not but it was still fascinating.
