Wow! What did I start!
Blade Runner, because here the released "Director's Cut" was not made by Scott, actually, but what the studio thought what he wanted. Hence the name "Final Cut" for when he actually got to do what he wanted; despite the reshoots he merely tweaked the original, something Lucas should take an example in.
Battleship Potemkin (1925/Former Soviet Union)
I have to say... this movie had me glued to the set from the very beginning. What has always been a sign of a great movie to me is if you get into a movie so intensely that it seems to be over within mere minutes of starting it. It seemed like I had just started the movie and it was time to switch over to disc two. And then before I knew it the movie was going off. It really is an excellent film. While I preferred the first half of the movie over the second half... the entire movie is just outstanding. Of course coming form me it isn't saying much... but this is definitely one of the best war movies I ever seen. The next time I am going to have to be sure to watch Apocalypse Now Redux.
