Bruce Banner’s poster
Here’s a quick tip for anyone who plans on binge-watching MCU films in search of easter eggs. If you want to see cross-references to other films, a good place to start is by looking at pictures or posters in the background. These are the easiest places for easter eggs to go unnoticed for months after the movie’s release.
Here’s a prime example. In Spider-man: Homecoming, Peter Parker’s classroom has posters of famous scientists on the wall. One of these is of Bruce Banner, also known as the Hulk. It’s weird that the science teacher would hang up a picture of Mark Ruffalo but whatever.
