- The Vision appears in a very conservative business suit, clearly meaning to visually reference another godlike, inhuman creation of science from a story of infighting among superheroes.

- During the airport fight, Ant-Man sneaks into Iron Man's suit and starts messing things up and taunting him, Iron Man confusingly asks who's speaking from inside his suit, Ant-Man replies: "It's your conscience. We don't talk a lot these days."
- The shot of Captain America's team and Iron Man's allies running towards each other at the airport looks very similar to the opening of Challenge of the Super Friends.
