Some might say... "No, checkerboard pants don't count...." Blah blah blah. But I'll have you know that they put in movies on shirts, blankets, pillows....
Here is Glenn Close (who probably has sacrificed babies in Hollywood) in that famous movie:
Notice how they film the tent as a pyramid (think logically), the pillow is a checkerboard and is purposely knocked over and then as she exits they show the child in a red shirt/sweater. Red shirt/sweater is one of the favorite child sacrifice emblems.
NOTE: Finding the checkerboard is only worth a few points. Finding examples of their child sacrifice passion is worth LOTS of points. Update if you find examples.
