I’d agree on Goodfellas. And I’d add Patton, Full Metal Jacket and Gladiator.
I originally had Patton and Downfall in the top 10 but then remembered how much the left hates Red Dawn and Green Beret's So, I had to do some reshuffling.
As for Full Metal Jacket, I thought the movie was good except for that slow motion scene where the bored looking VC girl kept killing the men running across the plaza in ultra slow motion. Gladiator was a good movie but I have to say I only watched it once so, it would probably be somewhere between my #11 and #20.
and Dr. Zhivago and Lawrence of Arabia...
