We're rounding third base as we enter the climactic final act of Marvel's promotional push for Avengers: Age of Ultron. Which means we're going to be seeing a fireworks display of interviews, clips and more from this upcoming sequel. Today, we have word from Joss Whedon about his newest character Quicksilver, as played by Aaron Taylor-Johnson. Talking with BUzzFeed from the set, he reveals that he was never 'thrilled' about 20th Century Fox also getting to use the character in last summer's X-Men: Days of Future Past, which featured Evan Peters in his breakout role. For better or worse, the director promises that his Quicksilver is very different from what we saw in that movie, and should not be compared to The CW's The Flash either. About Fox getting there first, though, Joss Whedon says:

"I think there's room for more than one Quicksilver. But yeah, I was never thrilled. There's going to be an entire season of The Flash that's gone on before my movie too, and what Aaron is doing and what I wanted him to do is so different from what they were doing in that movie, that I think we're fine."

Joss Whedon goes onto say that he had always planned on using Quicksilver and Scarlet Witch in his movie way before Fox announced that they would be utilizing the character as well. About Quicksilver being used by both Marvel and Fox, producer Kevin Feige admits:

"It's a unique scenario; That's the only character where that could happen, and it happened. We knew it would be very different based on the various interpretations of the character through the comic. It may as well be different characters."

Aaron Taylor-Johnson also talked about bringing his own interpretation to the popular Avengers and X-Men character. He knew he had to make it distinctive, and that proved to be a challenge. Especially since he had to spend a lot of his time on set sprinting on a treadmill. About the process he says:

"There was no real life to it. It looked really dull. The more dynamic or the messier my arms were or the wider my legs were, [and] the more I changed up the wave and the rhythm of the running, the better. It feels more emotional and expressive. It's a lot more fun that way."
