I am reading a book "The Power of Film" by Suber, Howard. In that he says, "In a great many films, most of the characterization occurs in the first act, the second act is usually devoted to action, and if there is any further characterization, it often doesn’t occur until the third act. If, however, the first act is devoted to action, it is too late to begin dealing with characterization in the second or third act." In the first statement, I don't understand what he means by "if there is any further characterization, it often doesn’t occur until the third act." I was under the understanding that characterization would normally come in 1st act and early part of 2nd act, but never thought it would come in 3rd act. Does anyone know what he means by that? Any film examples? As I don't understand the first statement, second statement is also confusing to me.
