I've been listening to Robert McKee's abridged audio version of his book "Story."

He claims that Raiders of the Lost Ark was in 7 acts (or maybe 8).

I have to grab my copy of the book and see if he goes into further detail.

But he's not exactly detail oriented. He says, "Remember the classic ending to Empire Strikes Back? Vader says, "Luke, you can't kill me! I am your father!"" And he talks about Luke's reaction to this is first to try to kill Vader (?). And then he gets his hand cut off (?). I think Mr. McKee needs to see the movie again.
