Avengers: Age of Ultron was released back in 2015, and while it was undeniably overshadowed by Captain America: Civil War, it remains one of the best entries in the Marvel Cinematic Universe.
Despite being a little muddled here and there (we're still not entirely sure what Thor's vision was all about), there's no denying that the epic final fight was a memorable one. That saw Earth's Mightiest Heroes assemble to battle a seemingly endless wave of Ultron's androids, and featured a stunning 360 shot as we circled the team while they blasted them apart.
Now, thanks to Marvel Studios concept artist Charlie Wen, we have a look at how that sequence was imagined during the pre-production stage. This was clearly pivotal in helping director Joss Whedon bring this scene to the big screen, and you can definitely see how it influenced what we saw.
Ultron remains on the minds of Marvel fans, but there's no indication that he will return to the MCU. If he was just a one and done baddie, though, he certainly made a lasting impact thanks to Age of Ultron.
