Paying homage to Arrested Development
While most of the easter eggs in MCU films only really reference other movies within the same universe, there are also subtle hints that we share the same universe as these superheroes. The references of pop culture franchises have nothing to do with Marvel, but they’re there.
In this picture, we see a stair car in the background in this Ant-Man scene. Fans of Arrested Development immediately noticed that the stair car looked exactly like Michael Bluth’s. As for why they had to have this exact car model in the background, we’re not exactly sure (except that the battle scene takes place at an airport).
