Last week on December 9th Guardians of the Galaxy was released on Blu-Ray and DVD, included in it's special features was a sneak peek at the upcoming film Avengers: Age of Ultron. The footage is only about two minutes long but revealed new Ultron concept art that looks absolutely maniacal..
Surfing the next I found screenshots of the concept art taken from a TV
This artwork definitely works well with the darker tone Joss Whedon has described the sequel to the 3rd highest grossing film in the history of cinema. I can't wait.
