The fight between the Flag-Smashers, Sam, Bucky, John Walker, and Lemar in the second episode was apparently one of the most difficult scenes to shoot. First of all, it was supposed to be in Germany but was shot in Atlanta. Also, it was all contained on two moving trucks, which is basically impossible in real life. So almost everything in the scene is visual effects—from the trucks, to the tires, to removing of wires, the mountains, basically everything, including the actors when it was necessary.
