Avengers: Age of Ultron introduced a few great new characters into the MCU. Two of them include Quicksilver and Scarlet Witch. I really liked these characters, and in separate interviews with Aaron Taylor-Johnson and Joss Whedon, they discuss the future of Quicksilver in the MCU.
I can't really talk about this without going into SPOILER territory, so you've been warned:
Those of you who have seen Avengers: Age of Ultron are probably thinking, “what kind of future does Quicksilver have!?” The character met his demise while running into some enemy fire, saving Hawkeye and an awkward little boy from being killed.
But Taylor-Johnson suggested in an interview with CinemaBlend that he may not be done with the character:
“I mean, I thoroughly enjoyed working on [this movie], and I would love to be doing more movies with the guys at Marvel. Maybe there will be some case where that might happen.”
After it was pointed to him that characters in the MCU return from the dead all the time, Taylor-Johnson responded:
“I’d love to find what that loophole is, because I think they’re the best guys I’ve worked with in a long time.”
The actor obviously really enjoyed his time working with Marvel, and he really wants to work with them again, but Whedon says he intended for Quicksilver to stay dead. Talking to the Empire Film Podcast, he said:
“It felt very disingenuous for me, especially the second time around, to make what I refer to as ‘a war movie’ and say that there is no price and everybody walks away. In this movie, we’re saying, ‘Prove to me that you guys are heroes.’ And he’s the guy that does it.
“I knew it would be resonant, and make everything else work better and matter more. The city in the air, that’s just an explosion… Wanda’s grief, that’s extraordinary.”
In the end it's not really up to Whedon if Quicksilver stays dead or not. That's up to the executives at Marvel and Disney. He did prepare for Quicksilver to live through the ordeal and even shot some alternate footage for the ending.
“I said to Aaron, ‘The only way you’ll stay alive is if the Disney executives say, ‘Hey idiot, this is a franchise, and we need all these people and you’re not allowed to kill them off!'”
“We did actually shoot him in the last scene, in an outfit, with his sister. We also shot him, waking up, saying, ‘Ah, I didn’t really die from these 47 bullet wounds!’”
As much as I enjoyed Quicksilver in this movie, I really hope that Marvel keeps him dead, otherwise his sacrifice means nothing. It would really take the power out of that scene. I'm done with the Marvel death fake-outs.
