Tom Hiddleston (Loki) greeting Mark Ruffalo's son. Ruffalo's son would come often to the set just to see Tom, saying "That was fantastic" after the cameras rolled. Hiddleston's response was "I'm doing this for you," later explaining that Mark's son made him realize how powerful these films really are, especially for kids.
