Visible crew/equipment: In the scene of the funeral for Arnold's wife and son, we hear the sounds of "Amazing Grace" being played on the bagpipes. There is a bagpiper in the distance, as the hymn goes on the piper can be seen blowing up his pipes and setting them under his arm without missing a note, which is physically impossible. When the camera pans to the gravesite, there is a second bagpiper in the foreground. He does the same exact thing, he blows up his pipes and sets them under his arm mid-tune with out missing a beat. When playing the bagpipes, you must fill the bag up with a certain amount of air to make the drones (the three pipes that come out of the bag and rest on the piper's shoulder) sound. You must then blow more air into the pipes to sound the chanter and play a tune. You cannot do what the bagpipers in this movie were doing and still play the tune.
