Top 5 Movies about Movies

I can't believe that neither Matt nor Adam had What Ever Happened to Baby Jane in their Top 5 movies about movies list? Is there no love for either Bette Davies or Joan Crawford? Or was is that they were too scared to see what was under on the covered dishes that Bette served to Joan?

For shame gentlemen, just watching two faded movies stars who hate each other, but are dependent on each other spiral in different directions, one in terror and the other into insanity, is so mesmerizing. If you haven't seen it, put it on the top of your queue.

P.S. I find it weird that so many people use Grand Guignol to describe this movie. It's like the French theater was built just for this movie.
