I was in acting class with a friend and my teacher talked about how some actors would do things for the roles they played. Such as one of the actors decided to gain some weight because he wanted to feel what it was like to feel rundown and out of shape. Another actor didn't sleep for 2 days and ran for 2hrs before coming in to do a torture scene because he wanted to feel what it would be like to be tortured. So my question is this: How do writers portray certain character personalities without doing the same method? Like the mind of an insane person, or even another gender. A lot of the time I read books and see an insane person. And even though sometimes well believable you realize how researched it was. And even some characters do sound researched[I don't have any examples because I am lazy and don't want to get up] rather then a character. Do you think writers would make better characters if they try this method? These are more hypothetical questions. Also wasn't certain to put this in general or character. So I put it in character.
