Re: The Design & Origin of ULTRON
Maybe Ultron will be our post credit's stinger if nothing else.
I can see it now, some classic dramatic zoom in on an AI program running on a SHIELD computer, or maybe even the actual robot. Everything goes red on the computer or we zoom in on the robot's face and the eyes go red while the thing boots to life with a menacing whir of robotics.
Fanboys in the audience roar with excitement while the less Marvel-educated (aka the general audience) are just like "wat".
