This may sound lame but you have restored my sanity. I first saw Alien when I was 9 years old. Later when I was about 14 or so I bought the novel and read it. There was a particular scene in the novel that described the "nest scene" or deleted scene.
As I read that part I could vividly see that scene in my mind as if I saw it on the movie itself. Many times seeing a movie first then reading the book often translates into you seeing images of the movie in your head as you read the book. The problem that I had was when I finally saw the movie for a second time, the nest scene was no longer in the movie. I often wondered and questioned in my head if I actually ever did see the scene or if it was just my mind putting together the scene in my head as I read the book.
Now some 28 years later I finally found out that I was not crazy and that scene was not something I imagined in my head that was created from the novel.
Thank you very much for that link. LOL
