Trust me. Drone better.
Justin Hammer recruits Ivan Vanko to assist him in making his Iron Man knockoff’s work. He puts Vanko to work in his factory in Queens, New York. The exterior and interior scenes at Hammer Industries (except the sequence with Black Widow and Happy fighting the guards) were all shot at Elon Musk’s SpaceX Building, in Hawthorne.
The shots where Black Widow and Happy break in, fight the guards and try to stop Vanko, plus Vanko in the server room were all shot on a soundstage.
