When Heather meets Wes at New Line, they talk about making a new movie to make Freddy stop.
At the end of this sequence, we can see that Wes is actually writing the script of "New nightmare". The dialog shown on the screen is literally what has just been said: (1:04:50)
This sequence ends with a fade to black, as written on the script.
I'm a bit confused about this part of the movie. At this point, is Wes both inside the movie, and writing the movie ?
