At the bridge sequence Tuco is shown loading his gun, and of course his gun is unloaded in the cemetary. Blondie says he unloaded the gun "the night before", but there was nothing to indicate a night passed between the bridge sequence and the graveyard. What gives?
The mad bit here though is that none of the soldiers woke them and said ' come on, we're off'. They just upsticked taking everything as quiet as churchmice leaving the two of them sleeping. A nice touch is the birds tweeting after the ferocity of the battle. Nature returns!
Half-Soldier: in the late 1960s the Cotton Industry had the adverising slogan "the more cotton, the better you feel" on their TV ads. When I watched GBU in 1968 and the doctor requests "more cotton" for the Captain, I couldn't help but wonder if that really made him feel better (but maybe it helped keep him alive long enough to hear the bridge explosion).
