The opening credits show young Natasha and Yelena being separated and moved with dozens of other girls through shipping containers at a container yard near a refinery.
This was shot at the container yards next to California Sulpher Company in Wilmington CA, looking at the refinery to the West. It was filmed in conjunction with Perception–the company that crafted the opening credit montage. Thanks to Doug at Perception for confirming the location.
