The whole post is good, but I want to pull this out:
"More often than not these long speeches have characters express in detail their emotions and attitudes. Not only is it taxing to listen to this balloon juice it also gives the actor nothing to play. Might as well go on to the next scene. Sometimes a look or a gesture can say volumes more a two page speech that James Joyce would find too convoluted."One thing I've found is that sometimes you come to the table with a speech that states your character's attitude/state of mind and, during the week, you cut it. But you needed it at the table (if it wasn't too long) so that the actor knew what they were playing. Once they know it, though, they can show, not tell.
