Given scene/plot descriptions from movies or TV shows, and given a specific question about the scene, summarize the question into a title

[Q]: In Wes Craven's New Nightmare, 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?
[A]: Is the script Wes Craven is writing on his computer the movie itself?


[Q]: While looking for various actors and actresses I keep coming across material they have done that isn't on their IMDB profile.   An example is Allison Scagliotti is in a web short yet there is no mention of it on her page, the web short did give her credit but this isn't always the case. I've noticed that music videos and web videos don't normally show up on IMDB as well as sometimes older roles that the actor/actress doesn't acknowledge.   Since IMDB is generally the go to for if an actor/actresses was in something. If it's not listed on IMDB or their wiki page (and in some cases I've come across not the actor/actresses own personal page) then how can I make sure if the actor/actress is the one I believe they are?
[A]: How to correctly identify an actor/actresses is in something that is not listed on their IMDB profile?


[Q]: In Saw 3, a sequence is shown where Dr. Lynn Denlon performs an operation on John (Jigsaw) using a drill and other similar tools.  My first question is, how can they perform an operation where hardware tools are used rather than medical instruments? Also, how can a person speak during his open brain surgery?  My second question is, is there any similarity between this operation sequence and reality?
[A]:
Is the brain sequence similar to reality or not?
