Silly asie: Did anyone else notice that in the last scene
with
Sellers playing Dr. Stangelove and doing his best to suppress his
Nazi salute, that the guy playing the Russian ambassador is
visibly struggling to hold back his laughter? I'd never noticed
it before, but it's there.


Yes, I have seen that. I also think George C. Scott's fall near the
middle of the movie was accidental, but left in, judging by the stupid
expression on his face when gets back up.
