In the film, scheduled for release in late August, Maddex struggles to convince adults that he is not a young boy but in fact a scaly, fire-breathing monster, Becker said. He convinces the doubters after transforming into the monster and stalking Chicago, discovering two monsters that are also on the loose. After battling them in Grant Park, Madzilla — true to 5-year-old form — lies down for a nap, Becker said. He declines to share much of what happens after that.
