Visually - the best are:
"Ran"  -  the burning castle during the war scene was maybe best ever
"Burnt by the Sun"  -  beautiful landscapes
"Que Viva Mexico"  -  too bad Eisenstein died before it was done
"Ivan the Terrible"  -  wow
"Othello"  -   By Orson Welles the first 5 minutes are the best black and white footage since sound
