Corrected entry: When Kikuchiyo impresses the Samurai by catching a fish, it's rather obvious that it's a dead fish that he grabs out of the water. A live fish would flop around and be gasping for water, but the fish he holds is completely motionless. Obviously this was done because it actually is QUITE difficult to catch a live fish in water.

Correction: The sequence was shot with live fish, as detailed in the extras on the Criterion Blu-ray release.
