Kaufman took meta-cognition to new levels...(spoilers)

I just watched this gem for the first time. I'm still reeling from it.

It's insane how many levels of consciousness this film is operating on. For example, when Donald comes in as Charlie's writing himself into the story, he then realizes it and says "oh no I'm writing myself into the story" or something to that effect.

1) He's referencing the fact that the real life Charlie Kaufman literally wrote himself into this movie

2) The fact that Cage is playing his twin brother and they're both in the frame when he says this is almost visually too much. This moment hit me so hard.

The levels of self-aware irony are just unprecedented. For example, the screenwriting guru that Charlie talks to tells him there needs to be drama and a change in the main character's being. Not long after that, the movie turns into a spoof chase/murder story where things get serious and Donald and La Roche end up dying.

At the end of the film, Kaufman has undergone a transformation in personality, making a move on the woman he loves and proclaims his love for her. So both of the things the writing guru told him to do with the script actually ended up happening in the actual movie. Of course this was intentional, but how Kaufman is able to philosophically puppeteer his own script like this is beyond me.

I'm sure there were so many other things that I didn't pick up on throughout that were just as novel, but I'm too mind blown at the moment to even try to recall them.
