I hate to keep harping on this point, but I have studied a bit of Hollywood history and nearly every movie goes through rewrites.
But I never said “movies don’t go through rewrites.” I said “comparing the process on The Rise of Skywalker to the process on the original Star Wars is a bad comparison.” And then I tried to support that claim by pointing out just how differently not only the process was, but the end results of those processes were. That claim doesn’t rely on the idea that movies don’t get rewritten, or that things don’t change between drafts. I’m not saying it doesn’t happen. I’m saying HOW it happened with THOSE TWO MOVIES is a bad comparison to make.
If you think anything any Star Wars movie has done script wise is unusual, you haven’t studied enough of the process.
This is also not true, sorry.
While you can say no two movies are exactly alike, you can also say that every movie goes through pretty much the same process. The variations are slight and it doesn’t matter if it takes months or years to go through the process. Some movies go through many different scripts by different writers and some movies go through many different scripts by one writer. And you can’t say which has had more changes because time and number of writers are not much of a factor.
