Remember, the whole world is watching.
After leaving the Flag Smasher Headquarters, John Walker chases Nico through a courtyard, and catches him in front of a statue where Walker makes a choice that will haunt him for the rest of his career.
This sequence was filmed at and around the Statue of Josef Jungmann in Prague. They characters run through the courtyard just East of the statue, before finishing up at the base of the Czech poet and linguist’s statue.
