Since it was announced that Joss Whedon would be introducing a number of new heroes in ‘The Avengers: Age of Ultron, fans have been clamoring for more details about Quicksilver, Scarlet Witch, and The Vision. After all, when all three of them were first introduced in the comics, they weren’t standing with Earth’s Mightiest Heroes right away. Will it be the same way when they make their Marvel Cinematic Universe debut? We have the answers!

In a recent report from Entertainment Weekly, Whedon weighed in on whose side these characters played by Aaron Taylor-Johnson, Elizabeth Olsen, and Paul Bettany will be on when his follow up to ‘The Avengers’ hits theaters next year:

“They’re on Team Ultron, which makes things really hard for the Avengers because all of sudden they’re dealing with powers that they’re not used to. With the [first] Avengers, everybody pretty much had the power of being able to punch somebody, and now we have a woman who can get inside your head and move objects, and a boy that can move faster than anything, and a robot [Ultron] who can self-replicate and is out of his mind. So all of sudden, it’s a darker, weirder, tougher world that they’re living in.”

Now that we know who they’re fighting for, the actors go into a bit more about their parts. First, Taylor-Johnson discusses the relationship between Wanda and Pietro Maximoff:

“They’re very yin-and-yang in that twin sense. In his power, he’s physical and she’s psychological. My character is very much on the frontline, but he can be quite emotional. You see this beautiful tenderness between them.

When you look in the comic books, you see a lot of the time that she’s always sort of mothering him. He’s like the father figure and she’s like the mother figure. Emotionally, she can stabilize him, and he protects her physically, vice-versa. So they have this beautiful connection and it’s kind of them against the world.”

Speaking of the comics, these siblings are always portrayed as being very close. In fact, some might argue that they might be too close. Olsen talks about exploring that on screen with her co-star:

“In the comics, every time you see an image of them, they’re always holding each other’s hand and looking over each other’s shoulder. They’re always so close, it’s almost uncomfortable. Aaron and I have been playing a little bit with those kinds of images just for ourselves.”

Finally, in regards to Vision, Whedon wouldn’t make a peep about the synthezoid due to spoilers, but the filmmaker did say that it’s not a coincidence that Bettany, who has appeared in past Marvel Studios films as the voice of Tony Stark’s personal artificial intelligence JARVIS, has been cast in the role.
