File under "things you don't normally notice" -
I was in a cafe/art district in Beijing. Outside the cafe I normally work at, they were filming a scene.
There were maybe 60 extras who just walked back and forth in the foreground/background a number of times.
All normal stuff so far - but then I noticed, all 60 of the extras ranged from looking and dressing from above average to beautiful.
I never noticed this before, but I bet the people in the foreground/background of most TV and movies would be similar. I'm going to pay attention next time I'm in front of a TV or at the movie theater and see if this is true.
