What is your favorite movie, and why?

I haven't been able to narrow it down yet. I have a few...1. Gone with the Wind, 2. Grease 3.Pretty Woman 4.The Runaway Bride 5. A Nightmare on Elm Street 6. Halloween 1&2 and the list goes on. Those are the movies that I can watch over and over again. I love them mainly because there is at least one character that draws me in or there is an actress or actor that stars in it that is one of my favorites in the business. That's six favorite and I not even mention movies with D.Barrymore and B.Davis.
