Concept Art for AVENGERS: AGE OF ULTRON - Early Ultron Prime Designs
Some additional concept art from Avengers: Age of Ultron has surfaced that shows off several early designs for Ultron Prime. Many of the designs are awesome, some of them hark back to the original comic book character design. I liked the final design that we saw in the movie, but I think some of these would have worked, too. They come from the "Art of the Movie" Avengers: Age of Ultron book. I’ve also included another piece of concept art above featuring the Avengers fighting off Ultron and his robot army. It was created and posted by artist Ryan Meinerding on his Facebook page.
