I don’t know that they were doing anything weird in the bullpen in Marvel, but certainly the stuff they were doing inspired all those people who were doing mind-expansion experiments at the time," explains producer Kevin Feige. "So, that's inherent to the property. And that's our mission statement for the visual effects on this movie." (Concept art, above)
