Yesterday, it was revealed that the villainous Ultron (James Spader) in Marvel's Avengers: Age of Ultron is planning to wipe out all of humanity, after being created by Tony Stark to lead a robotic intergalactic police force known as the Iron Legion. Today, we have more details regarding this highly-anticipated sequel from Entertainment Weekly's Comic-Con 2014 issue, which offer new insight into the creation of Vision (Paul Bettany), how director Joss Whedon is handling Scarlett Johansson's pregnancy on the set, plus new details about how Quicksilver (Aaron Taylor-Johnson) and Scarlet Witch (Elizabeth Olsen) fit into the story.

Marvel made the somewhat surprising announcement in February that Paul Bettany is playing Vision in Avengers: Age of Ultron, along with voicing Tony Stark's J.A.R.V.I.S. in the sequel. This report reveals that Vision's origins will stick closely to the comic books, with Ultron designing Vision, described as, "a synthetic, superpowered human," to show he has the power to create life.

While Joss Whedon wouldn't delve into specifics, the director would only say that it isn't a coincidence that the same actor who voices J.A.R.V.I.S. is playing Vision.

"It's not coincidence."

It's speculated that Ultron uses J.A.R.V.I.S.' consciousness as a part of creating Vision, but the filmmaker would not confirm. The director did say that Paul Bettany was "disappointed" that he had to actually show up on set, as opposed to recording his lines in a studio.

"By his own admission, Paul's very disappointed that he actually has to show up this time."

The director also mentioned that Vision is the fourth member of "Team Ultron," behind the villain himself and new additions Quicksilver (Aaron Taylor-Johnson) and Scarlet Witch (Elizabeth Olsen). When asked how these powerful twins fit into the story, Joss Whedon had this to say.

"They're on Team Ultron, which makes things really hard for the Avengers because all of a sudden they're dealing with powers that they're not used to."

Elizabeth Olsen also chimed in regarding her Scarlet Witch character, adding that she is not going crazy.

"It's not that she's insane, it's just that she's overly stimulated."

Aaron Taylor-Johnson reveals that Quicksilver has to play a dual role of father figure and brother to his twin sister.

"He's quick-tempered. He gets agitated. He's impatient. But he's super-protective. He had to become a father figure to his twin sister. He's physical and she's psychological. It's kind of them against the world."

Joss Whedon also addressed Scarlett Johansson's pregnancy, revealing that they did not trim any scenes because she is pregnant.

"She's not going to spend the whole movie carrying groceries. We didn't trim any scenes. We're like, 'We'll make it work.'"

The director revealed that they used three stunt doubles for Scarlett Johansson's more physical scenes, with each wearing digital markers on their faces so the actress' face can be digitally added in post production. Here's what Chris Evans had to say about the number of "Scarlett's" he would run into on the set.

"It's always funny. You walk by, 'Hey, Scarlett' --oh, weird. You're not Scarlett at all. Sorry. A lot of fake Scarletts around."

We know that Robert Downey Jr.'s Tony Stark creates Ultron from yesterday's report, but the actor also chimed in about the mindset of his character in the sequel.

"So to me, Iron Man was like a returning veteran going back to the nuts and bolts of what was always righteous about who he was. He was never a guy who didn't get his hands dirty. He was a tinkerer. He's a mechanic."

Yesterday's report also included details of a party scene at Avengers Tower, which is interrupted by Ultron where he reveals that all of humanity must be destroyed. We now have more details about the attack that follows, where Black Widow is seen firing at the robots in a "high-waisted cocktail dress that clearly covered her baby bump," while Bruce Banner tries to cover his ears to prevent another Hulk-out. There have been rumors that Black Widow and Bruce Banner have a romantic connection in Avengers: Age of Ultron, but that has not been confirmed.
