One of the more memorable fights in Avengers: Age of Ultron took place between two of the Avengers themselves: Iron Man, in his Hulkbuster armor, battled the Incredible Hulk in hand-to-hand combat. A Lego sculpture seen at Comic-Con 2015 recreates that sequence, and you can see it in video form courtesy of io9.
Notice that the person who captured the video appears to have zoomed in with his camera instead of getting up close and personal with the giant Lego figures. Better safe than sorry when these two knuckleheads are beating each other up.
