Called it
Allow us to show some appreciation for Jarvis, the AI assistant that aids Iron Man. In 2012’s The Avenger film, Hawkeye suggests shooting the incoming aliens down from corners as this would make the best use out of the enemy’s lack of mobility. Jarvis detects a corner route and sets up a course to it, as we can see on the bottom of Iron Man’s helmet display.
The AI assistant takes Hawkeye’s suggestion to heart despite being in the middle of battle. This isn’t exactly an easter egg, but it shows a huge commitment by both Jarvis and the film’s production crew.
