"This was the noblest Roman of them all. All the conspirators save only he, did what they did in envy of great Caesar. He only, in a general honest thought, and common will for all, made one of them. His life was gentle, and the elements so mixed in him that the nature might stand up and say to all the world, 'This was a man.'"
After all the battling and fighting and bloodshed, Mark Antony was able to look at Brutus and know he died an innocent man. He couldn't help doing what he did, because he thought he was doing it to save Rome. He had no ambition of usurping the throne (reminds me of those sly smiles of Mark Antony's...did he have ambition? Was he at fault more than Brutus, and was he able to recognize that?).
In the movie, next to Brutus' head was a lit oil lamp. Right before "The End" title comes on the screen, the flame is snuffed out. What does that mean? Merely that Brutus is dead? Or that the uproar of Rome has finally turned to peace? Or that Brutus' legend is not timeless and will eventually be snuffed out and that history will forget him?
One last note about the movie in general: it's interesting to me that the one Oscar it won in 1953 was for best art direction (for a black & white movie). To me, the set actually seemed basic and not extraordinary. Maybe I'm used to bigger-budget movies, but other than the large spaces the movie was able to fill I didn't feel like the scenery was anything too special.
