Leone intended there to be a double meaning, ie. that viewers should say that it could be viewed as a dream. But I don't think the intent was that some will say that it was not intended to be a dream
Thanks for contradicting yourself. It saves me the trouble.
Leone meant is that "all viewers should understand that there is a double meaning."
If Leone really meant that, then he failed terribly. Only a little minority has interpreted greater parts of the film as a dream.
Most people who have seen (and liked/loved) the movie have never heard of the dream theory Only a bunch of nerds like us know about it.

Regarding unrealistic parts of the movie, does anyone think it realistic in the beginning of the movie where Eve is killed, that they kill her so quickly? No interrogation, no hitting, no threats, no torture...like they had just been doing to Mo.
So the smile does come from the effects of the opium! Unless he is beginning to dream about the murder of Eve and smiles (unlikely). Or he is beginning to dream about the time he was in the john spying on Deborah (possible). Or he is dreaming backwards starting with Max jumping into the back of a garbage truck (just silly). It could be artistic and dramatic license again but even with opium, dreams take a while to start.
