Age of Ultron Synopsis (Spoiler-Light)
Tony Stark and Bruce Banner attempt to use the gem embedded in Loki’s scepter to create an artificial intelligence to protect the planet. This program becomes Ultron and believes that the best course of action to save the world would be to eliminate humanity’s ability to pose a threat. The Avengers must get together to try and stop him despite having enhanced siblings, a new synthetic ally, and some rifts within their team.
The film focuses mainly on the repercussions of actions. The idea that well-intentioned actions by Tony result in the issue they have to overcome is present in the rest of the MCU films.
The Core Avengers
These six heroes carry over from the first film, and each has a distinct arc in this sequel.
| Actor | Character | Role in the story |
| Robert Downey Jr. | Tony Stark / Iron Man | Co-creates Ultron and carries the guilt |
| Chris Evans | Steve Rogers / Captain America | Leads the team and clashes with Stark |
| Chris Hemsworth | Thor | Investigates the scepter’s power and returns with a crucial discovery |
| Mark Ruffalo | Bruce Banner / Hulk | Helps build Ultron and struggles with his bond with Natasha |
| Scarlett Johansson | Natasha Romanoff / Black Widow | Gets a quieter, more personal storyline |
| Jeremy Renner | Clint Barton / Hawkeye | Gets a much bigger role than in the first film |
What each core actor brings to this film
- Stark is played by Robert Downey Jr., who is more nervous throughout the film. Whilst there is some cockiness shown, the film uses his anxiety about an uncertain future.
- Rogers is played with a tougher edge by Chris Evans. His dynamic with Stark in this movie creates a bigger conflict in the overall MCU.
- The real star of the show was Jeremy Renner. In the first movie, Hawkeye was controlled for most of the movie; however,, in this one, he acts as the heart of the team. The farm scene really adds depth to a character who many have underestimated.
- The biggest surprise was Mark Ruffalo and Scarlett Johansson. They have some great chemistry together, and both characters are shown to be quite vulnerable. The Hulk has been given more depth and emotion in this movie.
Who Is the Voice of Ultron?
James Spader provides the voice and motion capture for Ultron.
The performance is really what makes the character special. Spader gives Ultron a very sarcastic, smooth, and menacing voice. This gives him a much more unique voice than the typical robotic, booming voice. The character likes to make jokes, give philosophical speeches, and pout. This makes him feel more like a flawed character, rather than a generic robot villain. This was quite divisive with some people but is a large reason why the character is memorable.
The New Heroes and Allies
Aaron Taylor-Johnson as Pietro Maximoff / Quicksilver
Pietro is a Sokovian with superhuman speed. Due to there also being a version of Quicksilver in the X-Men films (Played by Evan Peters), many people get confused between the two characters.
Elizabeth Olsen as Wanda Maximoff / Scarlet Witch
Wanda possesses telepathic and telekinetic powers. She isn’t given much of an introduction here; however, she went on to become one of the most important characters within the MCU. She became a huge talking point within WandaWiki-level fan forums. To get a good idea of where she appears in later films, refer to an official source.
Paul Bettany as Vision
Paul Bettany is a smart choice for this role. He previously provided the voice of J.A.R.V.I.S., the AI assistant to Tony Stark. In this film, he provides the voice of Vision, the synthetic lifeform created from Ultron’s body and J.A.R.V.I.S. code. This gives the character a sense of legitimacy, as it’s the same actor.
Supporting Cast: Who Played Who
Here are the secondary characters that viewers most often ask about:
- Don Cheadle as James “Rhodey” Rhodes / War Machine
- Anthony Mackie as Sam Wilson / Falcon
- Cobie Smulders as Maria Hill
- Samuel L. Jackson as Nick Fury
- Hayley Atwell as Peggy Carter (appears in a vision sequence)
- Idris Elba as Heimdall

- Claudia Kim as Dr. Helen Cho
- Thomas Kretschmann as Baron Strucker
- Andy Serkis as Ulysses Klaue
- Julie Delpy as Madame B
- Kerry Condon as the voice of F.R.I.D.A.Y.
Smaller roles that matter more than their screen time suggests
Linda Cardellini appears in short scenes as Clint’s wife, Laura Barton. This gives us more insight into what Hawkeye is fighting for.
Andy Serkis appears in a short role as arms dealer Ulysses Klaue. Whilst this is a short appearance, it ties in with the wider MCU, and the character will appear in future stories.
Claudia Kim plays Dr Helen Cho. Her cradle technology is vital in creating Vision.
Kerry Condon provides the voice for F.R.I.D.A.Y., who replaces J.A.R.V.I.S. as Stark’s AI assistant.
Cameos and Surprise Appearances
- Stan Lee makes his usual cameo, this time as a veteran at a party.
- Josh Brolin appears as Thanos in the mid-credits scene, a brief moment that points toward the larger story the MCU would tell over the next several years.
Common Mistakes When Looking Up the Cast
- Confuse Aaron Taylor-Johnson’s MCU Quicksilver with Evan Peters’ Quicksilver from X-Men films.
- Assume Vision is an entirely new voice, but he’s connected to J.A.R.V.I.S. by Paul Bettany.
- Confusing Avengers 2 with other Avengers movies. While there are some overlapping cast members between Avengers: Age of Ultron and future team-up movies, the roles are not as prominent. The supporting characters and villains change.
- Cameo roles are considered main roles. There are a handful of big names, but they’re only in a scene or two, so double-check with a reliable source if it’s a bet you’re trying to win.

Final Thoughts
The casting is a good choice as the majority of the ensemble have something to do. Jeremy Renner’s Hawkeye has some depth to his character while Paul Bettany links Vision to J.A.R.V.I.S. Furthermore, James Spader makes what could be a generic robot villain interesting.
Frequently Asked Questions (FAQs)
Who voices Ultron?
Ultron was voiced by James Spader. He used motion capture to portray him on screen, meaning that his character was portrayed on set by his acting, so he isn’t just doing a voice.
Is Avengers 2 the same as Age of Ultron?
Yes. Avengers 2 refers to Avengers: Age of Ultron. The official title has no ‘The’ in it. It is often referred to as ‘Avengers: The Age of Ultron ’.
Do I need to watch any other Marvel films?
Whilst you could watch The Avengers (2012) to get the main plot, Captain America: The Winter Soldier will give you extra background information. This explains why Baron Strucker is involved in the first few scenes due to Hydra. Whilst the Thor storyline may make more sense if you have seen previous Thor films, it isn’t necessary.
Is Tom Hiddleston in this film as Loki?
No. There is no appearance by Loki in this film. However, his scepter is central to the plot. If you want to know which actor played him, then check out the credits. Some actors from previous films are only mentioned.
