Marvel legend Stan Lee had a hand in creating many of the company's most iconic characters, and he's been recognized on the silver screen as a mainstay in the movies. With a cameo in nearly every Marvel movie and a running presence in the Marvel Cinematic Universe, it should come as no surprise that he'll appear in Avengers: Infinity War. So if we have other movies shooting on the same lot that we're on, for instance Ant-Man [and the Wasp] or Avengers 4, we group his cameos together and then move him from one set to the next and get him through his cameos in one day.
