Peyton Reed’s photo of the film could be teasing that Ant-Man and the Wasp will share a similar tone to it or there could be a sequence that pays homage to The Incredible Shrinking Man.
The Incredible Shrinking Man tells the story of an ordinary man who begins to shrink steadily every day thanks to getting exposed to a combination of radiation and insecticide.
The man continues to grow smaller, doing battle with cats and spiders as his world continually changes around him.
Perhaps there’s a scene where the duo needs to solve a crisis with household items while trapped at a small size.
