Avengers: Age of Ultron » Trivia (Movie)

Joss Whedon described this film as "smaller. More personal. More painful. The next thing that should happen to these characters, and not just a rehash of what worked the first time. A theme that is completely fresh and organic to itself."

Aaron Taylor-Johnson described his approach to Quicksilver as inspired by the "Marvel Ultimates" comic: "Him and his sister have been abandoned by their parents and they grew up in Eastern Europe defending and looking out for themselves and each other. His sister really is his guidance - emotionally she's the one who looks after him, and vice versa. He's very overprotective physically - he doesn't want anyone touching her."

Lt.James Rhodes aka War Machine has been in different teams of Avengers, The Avengers, the Westcoast Avengers and the Secret Avengers which was led by Steve Rogers aka Captain America

This film marks the first Marvel Cinematic Universe appearance of Tony Stark without Pepper Potts, with the exception of his cameo role in The Incredible Hulk.

Elizabeth Olsen described the Scarlet Witch as unstable: "She has such a vast amount of knowledge that she's unable to learn how to control it. No one taught her how to control it properly. So it gets the best of her. It's not that she's mentally insane, it's just that she's just overly stimulated. And she can connect to this world and parallel worlds at the same time."

It was planned that after this film was finished Robert Downey Jr. and Avengers 3, he would retire from the Marvel Cinematic Universe. However, Downey signed on for Captain America: Civil War (2016).

Lindsay Lohan sought to audition for the role of Wanda Maximoff.

Paul Bettany described the Vision as a nascent newborn: "He's both omnipotent and totally naive, the sort of danger of that and complex nature of a thing being born that is that powerful. The choices he makes morally are really complex and interesting."

Ultron starts out as as a peacekeeping force. This is a homage to his The Avengers: Earth's Mightiest Heroes (2010), where he had a similar origin.

This is not Aaron Taylor-Johnson's first time in a comic book movie. He previously played the title role of Dave Lizewski/Kick-Ass in both Kick-Ass (2010) and Kick-Ass 2 (2013).

In the first trailer, Ultron recites "No Strings On Me", a song from Pinocchio (1940), a Walt Disney film about an inanimate being who gains sentience; Ultron serves as a dark parallel of Pinocchio. Additionally, the song that plays during the trailer is a slowed down, spooky version of "No Strings on Me".

This is the first on-screen appearance of Tony Stark's Hulkbuster armor, which is seen in detail during the trailer.

The addition of Quicksilver to the cast sparked wide discussion over the direction of the character who is also slated to appear in X-Men: Days of Future Past (2014). Quicksilver had been discussed previously as a potential character in both X-Men: The Last Stand (2006) and The Avengers (2012), but legal complexities over the license to the character resulted in his omission from both films. However, in May 2013 both Marvel and Fox Studios announced a resolution to the previous legal issues, and that Quicksilver would appear in this film as well as an X-Men sequel, though under certain parameters: no allusion to his relations to the X-Men or Magneto (the character's father) can be made in an "Avengers" film, and no reference to Quicksilver's membership in the Avengers can be made in an "X-Men" film; the rights agreement between Fox and Marvel even goes so far as to stipulate the character cannot be referred to as a "mutant" in any Marvel film. Additionally, the day after Fox announced Evan Peters as Quickilver, Marvel and Fox entered into a legal standoff over provisions of the rights agreement for the character, including the issue of whether Peters would be allowed to portray Quicksilver in any other film outside the "X-Men" franchise, necessitating a second actor to play Quicksilver in any Marvel film, resulting in two different versions of the same character appearing in two competing film series.

In the trailer, Ultron compares himself to Pinocchio and despising Tony Stark as his father 'Gepetto'. It turns out that Robert Downey Jr. is playing the role of 'Gepetto' in a reboot of Pinocchio.

Robert Downey Jr. and other sources from Marvel Studios and Sony have mentioned discussions between the two studios for plans to bring Spider-Man into a film within the Marvel Cinematic Universe.
