When the first trailer for director Joss Whedon's Avengers: Age of Ultron debuted back in October, fans got their first real look at the villainous Ultron, voiced by James Spader. The eight-foot tall robot was created by Tony Stark (Robert Downey Jr.) to give the Avengers a much-needed break from fighting crime all over the world, but, as it turns out, Ultron sees all of humanity as a threat that needs to be eradicated. Filmmaker Joss Whedon recently spoke with Entertainment Weekly, where he compared Ultron's story to a classic horror creature.

"It's our new Frankenstein myth. We create something in our own image and the thing turns on us. It has that pain of 'Well, why was I made? I want to kill Daddy.'"

In crafting Ultron's plot, Joss Whedon referenced Ray Bradbury's story "The Small Assassin," where a small baby kills his parents. As for Ultron himself, while this monstrous robot contains the cumulative knowledge of all human history, Joss Whedon still compares his behavior to that of a spoiled child. Here's what the filmmaker had to say below.

"I don't remember seeing an artificial-intelligence movie where the robot is bonkers-the most emotionally unstable person in the film-and who has the knowledge of 3,000 years of recorded history and who is a pouty teen, all at the same time."
