You'll Never Get Rich Question

So I’m in the middle of watching You’ll Never Get Rich, and notcied something odd. When Fred Astaire and Robert Benchly are walking around the army camp, we see a bunch of people that appear to be gardening or doing groundswork. I notcied that everyone was pretending though. One person was flattening the soil with the bottom of a shovel, but he was holding it about 2 inches over the earth. Another was till, or turning the soil with a spade, but the tip never touched the dirt and another was sweeping with a pushbroom, but holding it just above the ground. The only reason I can figure for them to do this is that the microphones would pick up the sound. But you’d think they’d figure something out, it looks kinda silly. Like a grade shcool play.

When the movie was made, no one cared. They were looking at the stars, not the background.

I suggest you do the same. You’ll be much happier.
