My "Top 50 Movies of all time" list

I imagine that everybody's top fifty movies list would be quite unique. While individual movies would likely be found on multiple lists, finding a list exactly matching all fifty would be rarer than sharing their finger prints (I'm guessing). The first ten movies on my list are actually my current top 10. The next forty are in no particular order. I realize I have left off some very good movies, so feel free to share with me which ones that I missed.

This list is living and breathing, which is to say that I reserve the right to add and subtract from it as I see new movies (or remember worthy ones). My top ten movies are distinguishable from the rest in that they are timeless to me. I'm sure I have watched each of them at least a dozen times, and I could sit down and watch them from start to finish again today.

My first ten of the Top Fifty movies of all time:
1) The Jerk,
2) The Outlaw Josey Wales,
3) Jaws,
4) Forrest Gump,
5) Rocky,
6) The Princess Bride,
7) Star Wars,
8) Poltergeist,
9) The Buddy Holly Story,
10)Full Metal Jacket,

My next forty of the Top Fifty Movies of all time:
