A few shots - most noticeably the ending - are high-crane shots that pull back as someone walks away into the distance. This is a reference/spoof of Leone's high-crane shot in "Once Upon a Time in America."
When Tugg is back in his hut after his Simple Jack performance in the PoW camp, removing make up, and he turns to Halfsquat's knock is a direct reference to Deborah removing her make up when Noodles meets her again after all those years.
